## The Basis of Ohm's Law

Ohm's law deals with the relationship between current, resistance, and voltage. The equation stands for: V=IR, meaning voltage is equal to current times resistance. Voltage is measured as volts, current is measured in amps, and the resistance is measured in ohms.

## Calculating Ohm's Law

- In order to find the Voltage, you need to multiply IxR, which is current x resistance.
- In order to find the Resistance, you need to divide V/I, which is volts divided by current.
- In order to find the Current, you need to divide V/R, which is volts divided by resistance.

## Relations between Voltage, Current, and Resistance

- Voltage (potential difference) is the power.
- Current is the flow of electrons through the circuit.
- Resistance is what slows the current down in case it overpowers and blows.

When you have less resistance, there's more current going through the circuit since there's less repelling force. This is called inversely proportional.
