A Four-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. You can place up to four
resistors. Resistors can only be placed vertically.
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, Rseries
= R1 + R2 , and in parallel Rparallel = R1
* R2 / (R1 + R2) .
