By lumping Ohm’s law with joules law, one can easily achieve the formula for power. Let’s take a look at formulas: When current and resistance are given use V = IR to calculate voltage. Example #1: Find the voltage applied across 10 kΩ resistors when 5 mA current flows through it When current and power are given use V = P/I to find the volts.

Joule's Law of Heating. We know about the heating effect of current, when a current flows through an electric circuit due to collision between electrons and atoms of wire the heat is generated.

Now according to Joule’s law I 2 Rt = work done in joules electrically when I ampere of current are maintained through a resistor of R ohms for t seconds. By eliminating I and R in turn in the above expression with the help of Ohm’s law, we get alternative forms as.
