Response to the following problem :
For the circuit of Fig.
a. Find the total resistance, current, and unknown voltage drops.
b. Verify Kirchhoff's voltage law around the closed loop.
c. Find the power dissipated by each resistor, and note whether the power delivered is equal to the power dissipated.
d. If the resistors are available with wattage ratings of 1/2, 1, and 2 W, what minimum wattage rating can be used for each resistor in this circuit?
