Ohm's law

• Voltage = Current x Resistance
• The unit of resistance is the ohm (Ω).
• Resistance (R) = Voltage / Current
• Current (I) = Voltage / Resistance
• The equation for Ohms law is V = IR
• V is measured in voltage (V)
• I is measured in amps (A)
• Ohms Law states that the potential difference across a component is directly proportional to the current flowing through it.
• Power is calculated as P = IV
• P is measured in watts (W)
