(a) Use a sequence of source transformations and the lookback method to find the Thévenin equivalent at terminals A and B in Figure P \(3=51\).

(b) Then select a resistor to connect across A and B so that \(3 \mathrm{~V}\) appears across it.
(c) Suppose the 1-A current source is replaced by an ideal \(10-V\) voltage source with the plus side up. How does this alter the Thévenin circuit?
