Electrical Circuits (Simple)

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.

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

• increase
• decrease
• stay the same

Keeping the voltage constant, as the resistance of a circuit increases, the current will...

• increase

• decrease

• stay the same

In a parallel circuit which of the following is the same value throughout the circuit?

• Voltage
• Current
• Resistance
• Charge

The current going through the 45 ohm resistor is 

• 0.05 amps
• 0.2 amps
• 0.1 amps
• 5 amps

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

The ____________ is the energy that flows from the battery, through the wire in it’s path through the circuit.

• Electric Current
• Conductor
• Electromagnet
• Insulator

What would happen if an extra battery cell is added to a curcuit?
