Series Circuits Quiz

What is the main difference between series and parallel circuits?

• Parallel circuits do not have any loops.

• Series circuits have a single loop.

• Parallel circuits have a single loop.

• Series circuits have multiple loops.

What happens if one component in a series circuit is disconnected?

• The circuit continues to work.

• Only the disconnected component stops working.

• The whole circuit stops working.

• The voltage increases.

How is the total voltage in a series circuit determined?

• By dividing the voltages across all components.

• By multiplying the voltages across all components.

• By subtracting the voltages across all components.

• By adding the voltages across all components.

Where should an ammeter be placed in a series circuit?

• In series with the components.

• It doesn't matter.

• In parallel with the components.

• Outside the circuit.

How do you calculate the total resistance in a series circuit?

• By dividing the resistances of all components.

• By subtracting the resistances of all components.

• By adding the resistances of all components.

• By multiplying the resistances of all components.

If a series circuit has a total resistance of 6 ohms and a battery of 12 volts, what is the current?

• 4 amps

• 2 amps

• 1 amp

• 3 amps

What is the voltage across a component with 2 ohms resistance and 2 amps current?

• 2 volts

• 4 volts

• 8 volts

• 6 volts

How can you find the voltage across a component without using calculations?

• By using an ammeter.

• By using a voltmeter.

• By using a resistor.

• By using a battery.

Which component will have a higher share of the voltage in a series circuit?

• The component with the lower resistance.

• The component with the highest current.

• The component with the higher resistance.

• All components share the voltage equally.

Why do components with higher resistance get a higher share of the voltage?

• Because they are connected in parallel.

• Because they have lower current.

• Because they are closer to the battery.

• Because they require more force to push the charge through.
