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 …

WebJun 28, 2024 · One problem is that the current heats up the resistor. This increases the resistance, which means you don't get the exact current increase that Ohm's Law … WebJul 27, 2015 · Ohm's Law is NOT a universal law; in fact, if barely qualifies as a 'law' at all because, in most cases, it does not work! Nichrome alloy is designed to retain a … WebMar 31, 2024 · Nichrome is an alloy of nickel and chromium (it sometimes also has iron). Nichrome has a constant resistance so it shows a linear relationship between voltage and current and thus is an ohmic conductor. So, the correct answer is option B.
