A Two-Resistor Circuit

Increase/decrease the magnitude of the EMF and the resistors by clicking on the upper/lower part of the object. The values of the resistors range from 1 to 10 ohms. And the value of the EMF ranges from -10 to +10 Volts. Erase or replace the resistors by selecting the "Eraser" or the wire from the menu.
The current flowing through the circuit is defned as:
I = E / R .
The total resistance is determined as the sum of the resistors in series, thus
R = R1 + R2 .
