The relationship between volts, amps, and ohms is expressed in an equation known as ______________.

Explanation:
Voltage, current, and resistance are linked by Ohm's law. This law says V = I × R, so the voltage across a conductor equals the current through it times its resistance. If the resistance stays the same, increasing voltage increases current proportionally; changing the resistance scales the current accordingly. You can rearrange it to I = V / R or R = V / I to solve for any one quantity when the others are known. This relationship is the foundation for predicting circuit behavior and connects to power with P = V × I (also P = I^2 × R or P = V^2 / R). The other laws mentioned describe different phenomena: Lenz's law concerns the direction of induced currents, Joule's law relates to heat produced by current, and Faraday's law covers electromagnetic induction.
