When resistors are connected head-to-tail we say they are in series. The equivalent overall series resistance is the sum of the individual resistance values.
Created by Willy McAllister.
- Calculate the series equivalent resistor for the three resistors.
- Find the resulting current using Ohm’s Law.
- Find the element voltage across each resistor.
- Find the node voltage at each node (the voltage with respect to the ground node).
- Click on DC to simulate the circuit. The simulator shows you the node voltages.
- Challenge: Change any resistor values to get 1.00V at the top of R2.
