Circuits

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

The current going through the 45 ohm resistor is

• highest

• lowest

• the same as the 90 and 180 resistor

• zero

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

What is the total resistance (RT) across this circuit?

• 3 kΩ

• 10 kΩ

• 13 kΩ
