Combined Electric Circuit

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 has more than one path to flow through

In a parallel circuit if one light bulb goes OUT; then they ALL go out. TRUE OR FALSE?

• TRUE
• FALSE

Which best describes a simple series circuit?

• Electricity flows along one pathway.
• The flow of electricity comes from the switch.
• Electricity flows along many pathways.
• The flow of electricity comes from the light bulb.

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

What kind of circuit is this?

• series
• parallel

A correct statement of Ohm’s Law is:

• I= V R
• V ∝ I
• V = IR
• both b and c

The equivalent resistance in this circuit is 

• 100 ohms
• 450 ohms
• 400 ohms
• 30 ohms

The current going through the 90 ohm resistor is 

• 10 amps
• 0.1 amps
• 0.2 amps
