In a series circuit, if one component fails, what happens to the circuit?

• The circuit continues to function normally.

• The circuit becomes open and stops functioning.

• The circuit becomes a parallel circuit.

• The circuit's resistance decreases.

Which of the following is true about the total resistance in a parallel circuit?

• It is equal to the sum of the individual resistances.

• It is less than the smallest individual resistance.

• It is greater than the largest individual resistance.

• It is equal to the average of the individual resistances.

What is the unit of electrical resistance?

• Ampere

• Volt

• Ohm

• Watt

How does a multimeter measure continuity?

• By measuring the voltage across a component.

• By measuring the current through a component.

• By checking if there is a complete path for current flow.

• By measuring the resistance of a component.

What does a reading of zero ohms on a multimeter indicate when testing continuity?

• The circuit is open.

• The circuit is closed and has continuity.

• The multimeter is malfunctioning.

• The circuit has infinite resistance.

In a parallel circuit, how does the voltage across each component compare?

• It is different for each component.

• It is the same across all components.

• It is half of the total voltage.

• It is double the total voltage.

In a series circuit, how does the current through each component compare?

• It is different for each component.

• It is the same through all components.

• It is half of the total current.

• It is double the total current.

What is the effect on the total current in a series circuit if the resistance is increased?

• The total current increases.

• The total current decreases.

• The total current remains the same.

• The total current becomes zero.
