Find resistance formula
WebThe resistance formula is as follows: Resistance = voltage drop across a resistor/ current flowing through a resistor. R = \(\frac{V}{I}\) R = resistance (Ohms, Ω) V = … WebWhat is the formula for resistance? If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance R T = 9 volts / 3 amps = 3 Ω.
