For the circuit in Fig. 5.97, constructed of standard value resistors: Find the total resistance, current, and voltage across each element. Find the power delivered to each resistor. Calculate the total power delivered to all the resistors. Find the power delivered by the source. How does the power delivered by the source compare to that delivered to all the resistors? Which resistor received the most power? Why? What happened to all the power delivered to the resistors? If the resistors are available with wattage ratings of 1/2 W, 1 W, 2 W, and 5 W, what minimum wattage rating can be used for each resistor? FIG. 5.97

Explanation / Answer

d) R equivalent = 6 k ohm Current in the circuit = 120/6000 = 0.02A Power delivered by the source = E*i = 120*0.02 = 2.4J e) The total power dissipated across all resistors is equal to the power supplies by the source
