For the network of Fig. 6.74:
a. Find the total conductance and resistance.
b. Determine Is and the current through each parallel branch.
c. Verify that the source current equals the sum of the parallel branch currents.
d. Find the power dissipated by each resistor, and note whether the power delivered is equal to the power dissipated.
e. If the resistors are available with wattage ratings of 1/2, 1, 2, and 50 W, what is the minimum wattage rating for each resistor?
