Simple Ohms Law

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

• 1 Ohm
• 3 Ohms
• 4 Ohms
• 12 Ohms

What is resistance measured in?

• Ω (Ohms)
• V (Volts)
• A (Amps)
• W (Watts)

Current times Resistance equals
 (I X R)

• Power
• Voltage
• Amperage
• Ohm

Voltage divided by Resistance

(V / R)

• Current

• Power

• Ohms

• Watts

Voltage divided by Current

(V / I)

• Current

• Power

• Resistance

• Watts

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

• Increase
• Decrease
• Stay the same
• X

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

• Increase
• Decrease
• Stay the same
• X

How many Volts would we need to produce a current flow of 8 Amps through a 6 Ohm resistor

• 12 volts
• 24 volts

• 48 volts

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 word means how hard it is for electrons to flow through.

• Current
