Digital Multi Meter
Thevenin question, electronics help please?
If I had a D-cell battery from a torch and a Digital multi-meter(DMM). I've got nothing else to work with.
Could you please decribe an experimental method for finding the thevenin equivalent circuit of the flashliht battery?
Measure the open circuit voltage, V, and the short circuit current, i. The Thevenin voltage is the voltage you measured and the Thevenin resistance is V/i.
