Current in Series and Parallel

Multiple Choice

Which is a series circuit?

Multiple Choice

Which is a parallel circuit?

Multiple Choice

Look at the circuit. If the switch is CLOSED, what will happen if one bulb breaks?

• Other bulb will still work

• Both bulb will not work

Multiple Choice

Look at the circuit, an ammeter is placed around it. If the switch is CLOSED, what possible reading will it show?

• Ammeters will have different readings

• Ammeters will have same readings

• One ammeter will not show any readings.

Multiple Choice

Look at the circuit. Two more bulbs are added in series with other bulbs. If the switch is CLOSED, what will happen to the brightness of the bulb.

• The brightness stays the same

• The brightness will be dimmer

• The brightness will be brighter

Multiple Choice

Look at the circuit, if one bulb breaks, what will happen to the other bulb?

• It will still work.

• It will not work.

• It will work but it will be dimmer.

Multiple Choice

Look at the circuit, if one bulb in a separate branch is added, what will happen to the brightness of the bulb?

• The brightness will be dimmer

• The brightness will be more.

• The brightness stays the same/ no change.

Multiple Choice

Look at the circuit. Branch 2 is open, which statement is correct?

• Only the bulb in branch 2 will not work.

• All bulbs in other branches will not work.

• The first branch with two bulbs will still work, others will not.

Multiple Choice

Look at the circuit, the switch in the main branch is OPEN. Which statement is correct?

• All bulbs in all branches won't work.

• Only the first branch with two bulbs will not work. Others will still work.

• Only the second branch will work.

Multiple Choice

Look at the circuit. Ammeters are placed around it. What is the reason why there are different reading in different ammeters?

• The charges have different energies at each point.

• The charges become less as more bulb is added.

• The charges split up at separate branches then add up in the main branch.
