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.

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. … WebOhm’s Law provides a foundation of mathematical formulas that predict how electricity responds to certain conditions. [Figure 1] For example, Ohm’s Law can be used to calculate that a lamp of 12 Ohms (Ω) passes a current of 2 amps when connected to a 24-volt direct current (DC) power source.

WebOhm's Law does not have a problem here any more than any other formula in the sciences which involves dividing by a denominator which can go to zero. Ohm's Law exhibits a singularity when there is no resistance, but … 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. For capacitors and inductors, Ohm's law cannot used since their I-V curves are inherently not linear (not Ohmic). ... Ohm's Law Equations.
