Calculating resistance in a wire
Did you know?
WebR = ρ l A. Where, R is the resistance. ρ. is the resistivity of the conductor. l is the length of the conductor. A is the area of the cross-section of the conductor. From the above formula, it is understood that the resistance is directly proportional to the length of the conductor and inversely proportional to the area of the conductor. WebJan 13, 2024 · The parallel resistor calculator has two different modes. The first mode allows you to calculate the total resistance equivalent to a group of individual resistors in parallel. In contrast, the second mode allows you to set the desired total resistance of the bunch and calculate the one missing resistor value, given the rest.. To keep it simple, …
