Ohm's law

What unit is used to measure current?

• Ohms

• Omega

• Volts

• Amps

What unit is used to measure resistance?

• Ohms

• Omega

• Volts

• Amps

What is the formula for ohms law?

• 1+2=3

• R X E = I

• V =I x R

• E= MC squared

How do you calculate voltage?

• Current X Resistance
• Resistance ÷ Current
• Current ÷ Resistance
• Measure it with a ruler

What is the current in a circuit with 6 ohms of resistance and a battery containing 24 Volts?

• 1/4 A

• 144 A

• 4 A

• 0.4 A

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light

To complete a circuit the switch must be

• unattached
• open
• closed
• It depends

What is this symbol?

• resistor
• switch
• battery
• bulb

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
