Lesson 2 of 210 Deep dive

Ohm's Law: V = I × R

Voltage equals current times resistance - the single most useful equation in electrical design. Rearrange it to find any one value from the other two.

Quick check Tap an answer to check

If V = 12 V and R = 4 Ω, what is the current I?

Correct! I = V ÷ R = 12 ÷ 4 = 3 A
