Electrical Circuits

What are the two main types of circuits?

• Vertical circuits and horizontal circuits

• Single circuits and double circuits

• Circular circuits and square circuits

• Series circuits and parallel circuits

Which type of current periodically changes direction?

• Direct Current (DC)

• Static Current

• Alternating Current (AC)

• Unidirectional Current

Which type of current flows in one direction only?

• Direct Current (DC)

• Backward Current (BC)

• Alternating Current (AC)

• Random Current (RC)

Name a component commonly found in electrical circuits that stores electrical energy.

• inductor

• resistor

• transistor

• capacitor

What happens to the total resistance in a parallel circuit compared to a series circuit?

• Total resistance in a parallel circuit is greater than in a series circuit.

• Total resistance in a parallel circuit is less than in a series circuit.

• Total resistance in a parallel circuit is equal to in a series circuit.

• Total resistance in a parallel circuit is irrelevant compared to in a series circuit.

In a parallel circuit, if one component fails, what happens to the other components?

• The other components become more efficient.

• The other components increase in power.

• The other components continue to operate independently.

• The other components stop working immediately.

What is the unit of measurement for electrical resistance?

• Ohm

• Joule

• Ampere

• Volt

What is the purpose of a fuse in an electrical circuit?

• To increase the voltage in the circuit

• To decrease the resistance in the circuit

• To improve the efficiency of the circuit

• The purpose of a fuse in an electrical circuit is to protect the circuit from overcurrent.

How does alternating current (AC) differ from direct current (DC) in terms of voltage direction?

• AC changes direction periodically, while DC flows in one direction constantly.

• AC flows in one direction constantly, while DC changes direction periodically.

• AC and DC both change direction periodically.

• AC and DC both flow in one direction constantly.

Why is it important to use the correct voltage rating for components in a circuit?

• Using the wrong voltage rating enhances circuit performance

• Mismatched voltage ratings have no impact on circuit operation

• It is important to use the correct voltage rating for components to prevent damage or malfunction.

• Components can adapt to any voltage rating
