Electricity summary

What is Resistance?

• The flow of electrons
• Electric potential difference
• A battery
• The ability to reduce the flow of electrons

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light

If the Voltage is increased and the resistance stays the same, Current will

• Increase
• Decrease
• Stay the same
• X

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

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms

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

• A
• B

What would the voltmeter read
