Voltmeter ARTICLE

What is a key characteristic of a series circuit?

• The same current flows through each component.

• The voltage remains constant across all components.

• There are multiple paths for electricity to flow.

• The total resistance is less than any individual resistance.

How is a voltmeter connected in a circuit to measure voltage?

• In series with the component.

• In parallel to the component.

• Directly to the power supply.

• Using a current clamp.

What happens to the total resistance in a parallel circuit when more resistances are added?

• It increases.

• It decreases.

• It remains the same.

• It becomes equal to the sum of individual resistances.

Which instrument is used to measure current in a circuit?

• Voltmeter

• Ammeter

• Ohmmeter

• Multimeter

What is the formula for calculating total resistance in a parallel circuit?

• Rt = R1 + R2 + R3

• 1/Rt = 1/R1 + 1/R2 + 1/R3

• Rt = (R1 * R2 * R3) / (R1 + R2 + R3)

• Rt = R1 * R2 * R3
