EPROM means erasable programmable read-only memory. This is a type of PROM that can be completely removed or erased if it would be exposed to ultraviolet rays. Once the data has been erased, it can be reprogrammed so that new data can be stored. The EEPROM stands for Electrically Erasable Read Only Memory.


The data that will be stored here can only be removed if they are exposed to various electrical signals. These two can be easy to modify by users depending on the type of data that they would like to place on the RAM. Another difference between the two is that the EPROM would need to be removed from the computer so that the data can be removed. The EEPROM will not require this anymore.

Conserving electricity helps save a lot of money and also helps to reduce global warming. There are many ways to save the cost of electricity. One of the best ways to save electricity is to put off unnecessary lights. Make use of more natural light. You can also replace your regular bulbs with LED or fluorescent bulbs to save more.

Learn to unplug your appliance when they are not in use. It is also advisable to replace your old appliances with energy-saving appliances.

Embrace reusable energy such as solar or heat energy, take shorter hot showers, do most laundry with cold water.

Finally, learn to regulate the temperature of your fridge and refrigerator. This will increase the efficiency of refrigeration, which ultimately leads to less consumption of electricity.

CMOS and TTL are both classifications of integrated circuits. CMOS stands for ‘Complementary Metal Oxide Semiconductor’, while TTL means ‘Transistor-Transistor Logic’. The term TTL is gotten from the use of two BJTs (Bipolar Junction Transistors) in designing each logic gate. CMOS makes use of FETs (Field Effect Transistors) in the design. The basic advantage of CMOS chips over TTL chips is that it has a greater density of logic gates even within the same material.


A single logic gate in a TTL chip can be comprised of a large number of parts, as some extra components such as resistors are needed, while a CMOS chip with a logic gate can be comprised of just two FETs. Especially at rest, CNOS chips consume less power when compared to TTL chips. TTL chips are not really as delicate as CMOS chips when it comes to handling, because it is slightly vulnerable to electrostatic charge.

Single-Phase and Three-Phase Systems are the most common ways of transmitting power from one point to another. The electricity company uses these two ways of power distribution in transmitting power generated from the power plant to the transformer before it gets served into our different homes. However, there are differences between single-phase system and three-phase system. The first notable difference between them is, three separate currents are passed across the lines through the three-phase system, while single-phase system means, a single separate current is sent across the line.


This translates to the fact that, three-phase system uses three wires, including a neutral wire for its connection. Single-phase system uses just a wire and a neutral wire for its connection. Three-phase system, on the other hand, is usually used to distribute currents from the power plant to the transformer, while single-phase system is used to distribute electricity to various homes.

This efficient form of heating captures the natural warmth of the sun by allowing photons to knock electrons free from atoms. This generates electricity. The small units within the solar panels are called photovoltaic cells. Photovoltaic is a word that means the conversion of sunlight into elctricity.

It actually takes a large number of these cells all joined up together to make one star panel. They are like sandwiches, each slice of the sandwich receiving a positive or negative electrical change. The top layer of silcone gets phosphorous seeded to it which forms the positIve charge while the bottom layer gets boron for the negative charge. It is the combined result that produces electricity.

The correct option is option C.
The switch is the simple device that opens and closes an electrical unit.

Option D is wrong because an Ampere is the SI unit used to measure the flow of current across the surface at the rate of one coulomb per second. The ampere is used to measure electricity.

Option A is also wrong because a volt is used as a unit of electrical pressure which causes current to flow in a circuit.

Option B is wrong because a discharge is when the electrical energy from a charged body is removed such as batteries or capacitor.

The correct answer to this question is Its a path that lets electricity that does not let electricity pass through it well. In most instances, one wants to trap the heat and to slow down the flow. We also want to stop the flow to help prevent electric shocks.

There are many types of insulators around us every day, including wood, plastic, and ceramics. An example is a kitchen utensil like a spoon. The spoon is an insulator because it prevents the heat from the pan to spread to the hands. The wires of electrical appliances are also insulators so that the heat from the pan won't pass to the wires.

The correct answer to this question is B, Volt. The symbol for volt is V. It is an SI unit, and it is the difference between force. The name is in honor of physicist Alessandro Volta.

The measurement was named after him because he invented the voltaic pile, which was the first chemical battery. There are common voltages in batteries we use every day. In our remote controls, alkaline batteries are used.

A single alkaline battery that is unable to be recharged has a volt of 1.5. Another common voltage is in a mercury battery, which normally has 1.355V. Many of our cars use batteries, and that battery has a voltage of 12 V.

The correct answer to this question is C, Potential energy stored in a battery. Voltage is always a measurement between two points. These points are the positive and negative ends of a battery.

It can also be measured between a wire and a ground. The measurement of voltage is in volts. To mathematically calculate voltage, the following equation can be done: V=IR. I stand for current, and R stands for resistance.

When they are multiplied together, that is how the voltage can be found. There are two types of voltage. The first is DC voltage, which stands for direct current voltage. The second is the AC voltage, which stands for Alternating Current-voltage.

The correct answer to this question is E, Protons, Electrons Neutron. Each of these parts has its own charge. Protons are positively charged. Neutrons have no charge. Electrons are negatively charged.

Protons are with neutrons, while electrons orbit the nucleus. Atoms make up elements, and they are the smallest particles. Every element has a different number of protons. Overall, there are over 100 different types of atoms. Out of those 100, 92 of them are natural.

The rest are formed in labs. Forces are important parts of atoms. This is because forces are what hold protons, electrons, and neutrons to the atom.
