For the circuit shown in Figure 1:

a. Calculate the equivalent resistance, Req.

b. If a 5 A ideal current source is connected to the terminals on the left, what will the voltage

difference be across the source?

c. If a 5 V ideal voltage source is connected to the terminals on the left, what current will flow

through the source?

d. If a 5 V ideal voltage source is connected to the terminals on the left, what is the total

power that will be dissipated by all resistors in the circuit?
