Find the Thévenin equivalent resistance seen by R3 in Figure P3.23. Compute the Thévenin (open-circuit) voltage VT and the Norton (short-circuit) current IN , from node a to node b, when R3 is the load.
Find:
The Thévenin equivalent resistance seen by resistor , the Thévenin (open-circuit) voltage and the Norton (short-circuit) current when is the load.
Analysis:
(3) Leave the voltage source in and short circuit the load. Redraw the circuit and use mesh current analysis. Name the left hand mesh current I1, the upper right mesh current I2, and the lower right mesh current I3. All mesh currents are clockwise.

The subsequent problems deal with the circuit shown below. Assume that the diode is ideal (i.e., has a 0V forward bias voltage).
If VA=5V and VB=2V, and there is a switch that turns on both voltage sources at the same time, and there is no charge on the capacitor initially, what is current I immediately after the switch is closed (i.e., the circuit is not in steady state yet)?
A. 1/5 mA B. 5 mA C. 0 D. 1/3 mA E. 3 mA
