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! • This video is part of a full free course on electric circuits.
