What is Ohm's law?

Show ▼

Ohm's law states that V = IR, where V is voltage (volts), I is current (amps), and R is resistance (ohms).

How do you calculate current using Ohm's law?

Show ▼

I = V / R. Current equals voltage divided by resistance.

How do you calculate resistance using Ohm's law?

Show ▼

R = V / I. Resistance equals voltage divided by current.

What is the unit of electrical resistance?

Show ▼

The ohm (Ω), named after Georg Simon Ohm.

What is electrical power in terms of voltage and current?

Show ▼

P = VI, where P is power in watts, V is voltage, and I is current.
