Question

Define resisdence.write the si unit of resistence. Explain it.match the correct range of resistity with the material given conductoes insulator alloys

Answer 1

The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to the electric current whichflows through it: If the resistance is constant over a considerable range of voltage, then Ohm's law, I = V/R, can be used to predict the behavior of the material.ohm

The siemens (symbol: S) is the SI derived unit of electric conductance and admittance, also known as the mho (ohm spelled backwards, symbol is ℧); it is the reciprocal of resistance in ohms (Ω).
