Electric current is best defined as

• • The flow of protons through a conductor.

• • The movement of electrons in a circuit.

• A measure of the opposition to the flow of current in an electrical circuit

• • The accumulation of charges on a conductor.

The circuit is simple consisting of a battery, a resistor, and connecting wires. The electrical component that serves as the source of potential difference in the given circuit is

• Connecting wires

• The power supply

• Resistor

• Battery

The work done (energy transferred) when moving unit charge between two points is

• Potential

• Potential Difference

• Electric current

• Energy

The potential difference is measured using a

• Galvanometer

• Voltmeter

• Ammeter

• Both option (1) and (2)

The circuit is closed and includes a battery, connecting wires, and a resistor. Which of these components is not essential for the circuit to function?

• Battery

• Connecting Wires

• Resistor

• Both (a) and (b)

You wish to measure the voltage drop across the circuit. You will connect the voltmeter in

• Series

• Parallel

• Depends on the circuit design

• Both (a) and (c)

You connected the ammeter in series to measure the current flowing through the circuit. However, the ammeter is not showing any reading. Which of the following could be a reason for the ammeter not working?

• The ammeter is connected in series.

• The connecting wire is broken.

• The ammeter has an internal fault or is damaged.

• Both (b) and (c)

How does a resistor affect the working of a circuit?

• It increases the current flowing through the circuit

• It decreases the voltage across the circuit

• It reduces the flow of current in the circuit

• It converts electrical energy into mechanical energy.

What is the relationship between potential difference and electric current in a circuit?

• They are inversely proportional

• They are directly proportional

• There is no relationship between them

• Electric current is always greater than the potential difference

What is the role of a resistor in the given electrical circuit?

• To store electrical energy

• To provide a constant voltage

• To oppose the flow of current

• To provide a constant current
