What is the role of voltage in a circuit?

• To decrease the energy of electrons

• To provide a path for electrons

• To provide electric potential difference for charge to flow

• To stop the flow of electrons

What is the function of resistance in an electrical circuit?

• To increase the speed of electron flow

• To convert electricity into light

• To generate heat

• To slow down the flow of charge

Which description fits a series circuit?

• Current follows multiple paths

• Current does not flow

• Current flows directly from source to device

What characterizes a parallel circuit?

• Current follows a single path

• Current stops at each junction

• Current follows more than one path

• Current flows in a closed loop

What happens to the brightness of bulbs when more bulbs are added in a series circuit?

• The bulbs get brighter.

• The bulbs get dimmer.

• The brightness does not change.

• The bulbs turn off.

How does the current behave in a series circuit?

• Current increases with each additional bulb.

• Current decreases with each additional bulb.

• Current is the same throughout the circuit.

• There is no current in a series circuit.

What is the characteristic of voltage in a series circuit?

• Voltage increases across each bulb.

• Voltage is zero across each bulb.

• Voltage drop across each bulb.

• Voltage remains constant across each bulb.
