The difference is that AC circuits involve complex sources and impedances which vary with either time or frequency, so your V, I, & R aren't always real numbers, but complex expressions.

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.
