Does ohm's law apply to nichrome

WebThe unit of resistivity is then ohm-meters (Ωm). Nichrome, a non-magnetic alloy that is commonly made up of 80% nickel and 20% chromium, has a resistivity ranging from 1.10 … WebJan 9, 2016 · 2. 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. Nevertheless, the relationships established in Ohms Law for DC circuits will ALWAYS …
