Two experiments are conducted on the same Thevenin equivalent network, and the current, i, is measured for each case. What is the Thevenin equivalent voltage and resistance of the network?
Draw the two conditions showing Thevenin equivalent circuit as "V" and "R":
The drawing on the left shows that V must equal 5V if there is no current flow.
The drawing on the right shows that R must equal 5k to make the loop current 1mA.
