Series Circuit

Multiple Choice

In a series circuit, what happens to the current at different points in the circuit?

• It increases after each component

• It decreases after each component

• It stays the same throughout the circuit

• It stops after the first resistor

Multiple Choice

Three resistors are connected in series. If one resistor breaks, what happens to the rest of the circuit?

• The other resistors keep working normally

• The circuit continues with lower current

• The current increases in the other resistors

• The whole circuit stops working

Multiple Choice

If a 12 V battery is connected to three equal resistors in series, how is the potential difference (voltage) divided among them?

• Each resistor has a potential difference of 2 V.
• Each resistor has a potential difference of 4 V.
• Each resistor has a potential difference of 3 V.
• Each resistor has a potential difference of 6 V.

Multiple Choice

When resistors are connected in series, the total resistance of the circuit is:

• Less than the smallest resistor

• Equal to the largest resistor

• Equal to the sum of all resistors

• The average of all resistors

Multiple Choice

Why are decorative lights connected in series sometimes a problem?

• They draw too much current

• One broken bulb makes all the others go out

• Each bulb gets full voltage

• The current becomes different in each bulb
