WebWhen an ac circuit contains only resistance, Ohm's Law, Kirchhoff's Law, and the various rules that apply to voltage, current, and power in a dc circuit also apply to the ac circuit. …

WebThe amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm. Using Ohms Law, this gives us a flow (current) of 1 amp. Using this analogy, let's now look at the tank with the narrow hose. Because the hose is narrower, its resistance to flow is higher.

WebOhm’s formula is also valid for circuits with varying voltage or current, so it can be used for alternating current (AC) circuits as well.
