Ohm's Law

Front

What is current measured in?

Back

A (Amps)

Front

What is Resistance?

Back

The ability to reduce the flow of electrons

Front

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

Back

Decrease

Front

Current times Resistance equals (I X R)

Back

Voltage

Front

Voltage divided by Current (V / I)

Back

Resistance

Front

What is Ohm's Law?

Back

The relationship between voltage, current, and resistance: V = I × R.

Front

What unit is used to measure Voltage?

Back

V (Volts)

Front

What unit is used to measure Resistance?

Back

Ω (Ohms)

Front

What happens to current if resistance is decreased while voltage remains constant?

Back

Current increases.

Front

What is the formula to calculate Power in an electrical circuit?

Back

P = V × I (Power = Voltage × Current)
