Series Circuits Quiz

What is a series circuit?

• A circuit with components on separate branches

• A circuit with multiple batteries

• A circuit with components in one loop

• A circuit with no components

What happens to the current in a series circuit?

• It decreases as it moves through the circuit

• It is the same in all parts of the circuit

• It stops at each component

• It increases as it moves through the circuit

What happens when you add a second bulb to a series circuit?

• The circuit breaks

• Both bulbs become dimmer

• The first bulb becomes brighter

• The second bulb does not light up

If a bulb breaks in a series circuit, what happens to the other bulbs?

• The other bulbs become brighter

• The other bulbs stay lit

• All the bulbs go out

• The circuit becomes faster

What is the unit of current?

• Watts (W)

• Ohms (Ω)

• Volts (V)

• Amps (A)

What is resistance?

• The speed of the current

• How difficult it is for current to flow

• The brightness of a bulb

• The energy of a battery

What is potential difference measured in?

• Watts (W)

• Volts (V)

• Amps (A)

• Ohms (Ω)

What happens to the total resistance when more components are added in series?

• It becomes zero

• It stays the same

• It decreases

• It increases

What is the role of a switch in a series circuit?

• To make or break connections

• To increase the current

• To change the voltage

• To decrease the resistance

How is potential difference shared in a series circuit?

• It is shared between components

• It is only across the first component

• It is the same across all components

• It is only across the last component
