WebMar 31, 2024 · Concept: Resistance (R): The resistance offered to the flow of current is known as the resistance. SI unit of resistance is the ohm (Ω). Mathematically resistance … WebAnswer (1 of 7): Resistance R=rho×Length/Area, where rho is the resistivity. This is an algebraic equation that can be solved by rearranging the terms, Length= R× Area/rho. The units must be consistent. If rho is in Ohm-meters the the area must be in meters squared and the length in meters. You...
WebMar 26, 2024 · For manganin, the temperature coefficient of resistance is very low and its resistivity is quite large. Due to which the resistance of manganin wire remains almost unchanged with change in temperature. It is due to this fact, the wire of manganin is used for making standard resistance coils. Q.6.
