WebApr 24, 2015 · 2. When you have a fixed voltage and unknown current, you should re-state Ohm's law this way: I = V R. Since V is constant and finite, then you can see that. lim R → ∞ I = lim R → ∞ V R = 0. . So even though R is never quite infinite, Ohm's law still shows that the more you increase R, the closer I gets to zero. Share.

WebScore: 4.1/5 (38 votes) . We can use Kirchhoff's voltage law when analysing series circuits.When analysing either DC circuits or AC circuits using Kirchhoffs Circuit Laws a number of definitions and terminologies are used to describe the parts of the circuit being analysed such as: node, paths, branches, loops and meshes. WebJan 8, 2016 · Simple answer: Yes, Ohm's Law still applies in AC circuits. 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.
