Electricity C.A.T

A series circuit will continue to work if one of the light bulbs is unscrewed.

• true

• false

This is an example of what type of circuit?

• simple

• series

• parallel

Each time a lightbulb is added to a series circuit, the other bulbs in the circuit 

• get brighter
• get dimmer
• stay the same brightness
• release more heat

A group of lights are connected in a parallel circuit.  One of the lights is removed.  The rest of the lights will

• get brighter
• get dimmer
• go out
• not change

Which of the following represents Ohm’s law?

• I = V / R

• V = I x R

• R = V x I

• V = I / R

What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V
• 10 V
• 2.5 V
• 0.4 V

This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

• 3 Amps
• 192 Amps
• 2 Amps
• 4 Amps

What size resistor would produce a 3 Amp current flow with a 12 Volt battery

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms

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

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C
• Point B to Point C
• Point A to Point D
• Point B to Point D
