Ohm's Law

How do you calculate current

• Resistance X Voltage
• Voltage X Resistance
• Resistance ÷ Voltage
• Voltage ÷ Resistance

What voltage is needed to cause a 2A current flow through a 10Ω resistor?

• 5V
• 0.2V
• 20V
• 200V

What resistance is needed to cause a 50A current flow because of a 500V battery?

• 10Ώ
• 5Ώ
• 2500Ώ
• 550Ώ

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

• Current

If the battery produced 12.6 Volts and what would be the current flow be for a 6 Ohm resistor

• 2.1 Amps
• 2.4 Amps
• 1.71 Amps
• 15 Amps

What is current 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

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

• Increase
• Decrease
• Stay the same
