Series

If the switch was opened, what would happen?

• the ammeter would measure a current flowing

• current would no longer flow, so everything would be off

• the bulbs would stay on because they're connected to the cell

• the bulbs would burn out and catch fire

This is an example of a _______ circuit

• open

• series

• parallel

• square

The total resistance in this circuit is 

• 100 ohms

• 450 ohms

• 400 ohms

• 30 ohms

When the second bulb is added, they get

• brighter

• dimmer

• broken

• cold

What is the measuring device shown?

• bulb

• cell

• ammeter

• voltmeter

Which component provides the energy for the charges?

• cell

• bulb

• switch

• ammeter

If the current flowing through the cell is 2A, what is the ammeter reading?

• 5A

• 1A

• 6A

• 2A

As resistors are added in series to a circuit, the total resistance will...

• increase

• decrease

• stay the same

The fault in this circuit is the:

• Ammeter

• Cell

• Bulb

• There is no fault.

In this circuit, the bulb(s) that light up are:

• 1 only

• 2 only

• 1 and 2

• None of them
