The picture shown here is
-
Motor
-
Fan
-
Solenoid
-
Switch
Correct Answer
A. SolenoidExplanation
The correct answer is solenoid because a solenoid is an electromechanical device that converts electrical energy into linear motion. It is commonly used in various applications such as valves, locks, and relays. The picture shown here resembles a solenoid, with its cylindrical shape and wires wrapped around it. The other options, motor, fan, and switch, do not accurately match the image provided.Rate this question:

The name of the element inside a glass bulb is
-
Hot element
-
Cold element
-
Resistive element
-
Non of the above
Correct Answer
A. Resistive elementExplanation
A resistive element is the correct answer because it refers to a component that has resistance to the flow of electric current. In the context of a glass bulb, a resistive element could be a filament or a wire that produces heat and light when an electric current passes through it. This element is commonly found in incandescent light bulbs and is responsible for producing the illumination.Rate this question:

A reistor is used in a electric circuit is for
-
Limiting the electric current
-
Increasing the electric current
-
To hold the electric current
-
All of the above
Correct Answer
A. Limiting the electric currentExplanation
A resistor is used in an electric circuit to limit the electric current. It does this by providing resistance to the flow of current, which helps to regulate and control the amount of current flowing through the circuit. By limiting the current, resistors help to protect other components in the circuit from damage due to excessive current flow.Rate this question:

The resistor is fabricated by carbon material
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is stating that the resistor is made of carbon material. This means that the resistor is most likely a carbon resistor, which is a common type of resistor used in electronic circuits. Carbon resistors are made by mixing carbon powder with a binder material and then shaping it into a cylindrical form. The carbon material provides the resistance to the flow of electric current. Therefore, the statement is true.Rate this question:

A buzzer is used to get sound as an output
-
True
-
False
Correct Answer
A. TrueExplanation
A buzzer is an electronic device that is designed to produce sound when an electric current is passed through it. Therefore, it is used as an output device to generate sound. This statement is true because a buzzer is indeed used to get sound as an output.Rate this question:

Solenoid make circular mechanical motion
-
True
-
False
Correct Answer
A. FalseExplanation
The given statement is false. Solenoids do not make circular mechanical motion. A solenoid is an electrical device that converts electrical energy into linear mechanical motion. It consists of a coil of wire that generates a magnetic field when an electric current passes through it. This magnetic field causes a plunger or armature to move linearly within the solenoid. Therefore, solenoids produce linear motion, not circular motion.Rate this question:

Motor makes rotational motion
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true because motors are devices that convert electrical energy into mechanical energy, causing rotational motion. Motors typically consist of a rotor (the rotating part) and a stator (the stationary part), and they work based on the principle of electromagnetic induction. When an electric current is passed through the motor's coils, it creates a magnetic field that interacts with the magnetic field of the permanent magnets in the motor, causing the rotor to rotate. Therefore, motors are commonly used in various applications where rotational motion is required, such as in electric fans, washing machines, and vehicles.Rate this question:

When current is passed throug a solenoid, it turn to magnet
-
True
-
False
Correct Answer
A. TrueExplanation
When current is passed through a solenoid, it generates a magnetic field. This magnetic field causes the solenoid to behave like a magnet, with a north and south pole. This property of solenoids is used in various applications such as electromagnets, transformers, and inductors. Therefore, the statement "When current is passed through a solenoid, it turns into a magnet" is true.Rate this question:
