WebOhm’s Law Formula. Voltage= Current× Resistance. V= I×R. V= voltage, I= current and R= resistance. The SI unit of resistance is ohms and is denoted by Ω. This law is one of the most basic laws of electricity. It helps to … WebApr 4, 2024 · If two positive unit charges are separated by a distance of 1 m, then from coulomb’s law we get the force of repulsion as $9\times {{10}^{9}}\text{ N}$. So, we can define a unit charge as two similar charges that should be placed at a distance of 1m apart in order to get a Coulomb’s repulsive force as $9\times {{10}^{9}}\text{ N}$.
