Voltage

Which one is a series circuit?

• 
• 
• 
• 

Which one is a parallel circuit?

• 
• 
• 
• 

Why voltage is important?

• Because it is the pressure that causes the electrons to move around in a circuit and make the current flow and make appliances work

• To supply energy to be able to make the current flow in electric circuit and make appliances work

• To control the resistance in the circuit

• To reduce the current in the circuit

What is the unit used for voltage?

• Ampere

• Ohm

• Volt

• Meter

How do aligned batteries affect voltage?

• More volts means less power

• More volts means more power

What is the difference between volts and voltage?

• Voltage is the pressure and Volts are the units to measure that pressure

• Volts is the pressure and Voltage are the units to measure that pressure

Why would two lights on the same circuit be dimmer than a single light bulb?

• They share voltage and thus reduce the power.

• They share voltage and thus increase the power.

As the resistance of a circuit increases, the current will

• increase

• decrease

• stay the same

• increase and then decrease

How many Volts would it take to push 5 Amps through a resistance of 10 Ohms

• 10 volts

• 1 volt

• 50 volts

• 5 volts

If the current through a circuit is 2 A and the resistance of a light bulb in the circuit is 10 Ohms, what is the voltage difference across the light bulb?

• 5 V
• 12 V
• 0.2 V
• 20 V
