Electric Circuits Quiz

Question 1 of 7

1

In a simple series circuit, why does the bulb light when you close the switch?

Select one of the following:

  • Because the switch produces electricity .

  • Because closing the switch completes the circuit.

  • Because closing the switch breaks the circuit.

  • Because voltage flows through the circuit.

Explanation

Question 2 of 7

1

A simple series circuit consists of one 1.5V battery, wires and one bulb.
When the1.5V battery is replaced with a 3V battery:

Select one of the following:

  • the bulb glows brighter.

  • the bulb glows with the same level of brightness.

  • the bulb glows dimmer

  • the bulb "blows" and the circuit will no longer work.

Question 7 of 7

1

Why is a bulb brighter when it is powered by two batteries in series rather than by just one battery?

Select one of the following:

  • Because the flow of electric current in the circuit is less.

  • Because the flow of electric current in the circuit is greater.

  • Because the flow of voltage in the circuit is greater.

  • Because the total voltage across the circuit is less.
