What are the 4 basic unit of electricity in ohm's law?

These are the four basic units of electricity:

• Voltage (V)
• Current (I)
• Power (P)
• Resistance (R)

Answer

Ohm's Law states that 'the current drifting in a conductor is directly-proportional to the potential difference across the ends of that conductor, providing all physical conditions, such as temperature, remain constant'.

As you can see, therefore, only two (not four!) quantities, current and voltage, are specified. So only two units of measurement apply: the ampere and the volt.
