Ohm’s Law Example #1

This tutorial shows how to determine the current in this simple series resistor (voltage divider) circuit using Ohm's law. We use the principle of voltage division to first find the total circuit resistance of the three series resistors, and then rearrange Ohm's law (V=IR) to get the I=V/R, ie, the total current is equal to the total voltage divided by the total resistance. The current through each resistor will be equal to the total current, as there is only one path for the electric current to follow.

At 2:03 I write 39Ω but say "39 volts" ... I meant to say "39 ohms." Sorry if that confused anyone!

How do you find a resistor if it is not given? For example if R3 was not given but you had R1 and R2
