• Power source, conductors, load

• Battery, switch, diode

Name three types of circuit components and their functions.

• Transistor, Diode, Transformer

• Microcontroller, Resistor, Capacitor

• Resistor, Capacitor, Inductor

• Battery, Switch, Fuse

What is the purpose of a resistor in a circuit?

• To convert electrical energy into heat.

• To limit current and control voltage in a circuit.

• To store electrical energy for later use.

• To increase current flow in a circuit.

How does a capacitor store energy in an electric circuit?

• A capacitor stores energy as heat in its wires.

• A capacitor stores energy by converting it into chemical energy.

• A capacitor stores energy in an electric field created between its charged plates.

• A capacitor stores energy by creating a magnetic field around it.

What symbol is used to represent a battery in circuit diagrams?

• Two parallel lines, one long and one short.

• A single circle with a plus sign

• Two overlapping squares

• A zigzag line with a dot

Explain the difference between series and parallel circuits.

• Series circuits have a single path for current, while parallel circuits have multiple paths.

• Series circuits can operate independently, while parallel circuits cannot.

• In series circuits, the voltage is divided, while in parallel circuits, the current is divided.

• Series circuits have multiple paths for current, while parallel circuits have a single path.

What does Ohm's Law state about voltage, current, and resistance?

• I = V - R

• Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

• R = V + I

• V = I / R

Why is it important to use a fuse in an electrical circuit?

• Fuses help to improve the efficiency of electrical appliances.

• Fuses are used to increase the voltage in a circuit.

• It is important to use a fuse in an electrical circuit to protect against overcurrent and prevent damage or fire.

• Fuses are only necessary for high-power devices.

What safety precautions should be taken when working with electricity?

• Work in wet conditions for cooling

• Use metal tools for better conductivity

• Wear PPE, use insulated tools, avoid wet conditions, turn off power, and be aware of surroundings.

• Ignore power sources around you

What is the function of a circuit breaker?

• To increase the voltage in electrical circuits.

• To enhance the performance of electrical devices.

• To protect electrical circuits from overloads and faults.

• To provide a constant flow of electricity.
