1. The problem statement, all variables and given/known data A real voltage source is of the Thevenin Type. The open circuit voltage of the source is 12 volts. If a 100 ohm load is added to the circuit, the voltage at the same terminals is 11.2 volts. What is the internal resistance of the source. 3. The attempt at a solution I found the total current in the circuit to be 12/100 = 120mA If there is .8 volts missing, the internal resistance should be: .8/120mA????
