Example of high resistance in a circuit

WebDec 23, 2024 · A high electrical resistance of an electrical conductor is the opposition to the flow of an electric current through that conductor; the inverse measure is known as electrical conductance. The SI unit of electrical resistance is the ohm (O). The property of high electrical resistance has important applications in electrical and electronic ... WebFor example, power-handling ability of a resistor may be greatly derated when applied in high-altitude aircraft to obtain adequate service life. A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance ; this causes large voltage spikes, which may exceed 500 volts.
