Electricity Questions and Answers (Q&A)

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.

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.

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.

A is the answer to this question. There are a lot of people who may have experienced static when they brush against another person or another item. Some electric charges will stay on the surface of the product and they may not be balanced. This explains why there are instances when you will feel that electricity will flow between you and another object.

Remember that the charge will remain on one surface unless it will already change due to its exposure to another object. There are different reasons why static electricity may build up. If you would rub your socks on the carpet, this will start to build static electricity. There are still other examples that are available.

If you have ever worn a silky skirt or light pair of pants, you may have been subjected to the pants leg sticking together. It is a little embarrassing. You will constantly be pushing your pants leg or skirt down. This is because there is static electricity in the clothing.

The cause of this static electricity is that one part of the pant’s leg is very resistant to electric current. There also may be too much of the positive charge on one side of the pant’s leg, but there is the same amount of negative charge on the other side of the pant’s leg. The imbalance is what causes the static electricity.

Also, your hair may stick up if there is static electricity.

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.

Electricity powers many homes and apartments. In order to get electricity, a homeowner must contact the electric company in their area and sign up for electricity. Ever month the meter is read outside of the home to determine the amount of electricity used. Some seasons and weather make people pay higher electric bills.

In some areas of the country, winter causes higher electric bills because it takes more heat to heat the entire house. There are some ways to save electricity so that the bills will go down. Some people will buy gas logs and put them in their fireplace. This helps to heat the house more. Also, turn off all of the lights when leaving a room in your house.

Electrons are found in the cell nucleus. They have a negative charge and they have a mass of 1/1836 of at the proton. The protons have a positive charge and are also found in the cell. When electrons and protons come close, they are attracted to each other. If they were not, then the electrons would move away from the nucleus.

Each nucleus needs the appropriate amounts of electrons that are needed in the atom to make it what it is supposed to be. If the electrons flew away, the atom would not be what it is supposed to be. Therefore, keeping the electrons in the nucleus by making the protons attracting them will make the atom stay the same.
