Q13-Q18

What unit do we use to measure how much electricity is flowing through a circuit?

• Volt (V)

• Ampere (A)

• Ohm (Ω)

• Watt (W)

What kind of circuits are used to wire up our houses?

• Series circuits

• Parallel circuits

• Both series and parallel circuits

• Neither series nor parallel circuits

What is the main advantage of parallel circuits in homes?

• They use less wiring

• They allow components to continue working if one fails

• They make the lights dimmer

• They are easier to build

What is the abbreviation for volt?

• V

• A

• Ω

• W

What is the main advantage of series circuits?

• They use less wiring

• They allow components to work independently

• They are brighter

• They are more expensive

What happens to the current if you increase the voltage across a circuit?

• The current decreases.

• The current stays the same.

• The current increases.

• The circuit stops working.

What is a parallel circuit?

• A circuit with components in a single line.

• A circuit with components on different branches.

• A circuit with no components.

• A circuit with only one lamp.

What is the result of decreasing resistance in a circuit?

• The current decreases.

• The current increases.

• The voltage decreases.

• The circuit stops.

What happens to the current if you increase the resistance in a circuit?

• The current increases.

• The current decreases.

• The voltage increases.

• The circuit becomes brighter.

What happens to the current if you add more bulbs in a series circuit?

• The current increases

• The current decreases

• The current stays the same

• The current stops
