Back

Current X Resistance

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) is defined as V = I × R.

Front

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

Back

Current will double.

Front

What is the formula to calculate resistance?

Back

Resistance = Voltage ÷ Current

Front

What is the unit of measure for resistance?
