Key concepts
3 concepts
- 1
Voltage is the potential energy in electricity, and it is measured in volts.
- 2
Ohm's Law describes the relationship between voltage, current (I), and resistance (R) with the formula: V = I * R.
- 3
As resistance increases, the current decreases, and as voltage increases, the current increases.
