Question: The indirect method is used to determine total power in a parallel circuit when that power is determined from the total current, total resistance, and source voltage.

Answer: False

Question: The indirect method is used to determine total power in a parallel circuit from the sum of the individual power consumptions of the loads in the circuit.

Answer: True

Question: Indicate the correct formula for determining the total power consumption of the circuit directly, when you know E (volts) and I (amps).

Answer: D. P(T) = E(T) x I(T)

Question: Indicate the correct formula for determining the total power consumption of the circuit directly, when you know I (amps) and R (ohms).

Answer: D. P(T) = I(T)^2 x R(T)

Question: Indicate the correct formula for determining the total power consumption of the circuit directly, when you know E (volts) and R (ohms).

Answer: D. P(T) = E(T)^2/R(T)

Question: How much power would be consumed in a parallel circuit that has a source voltage of 300 volts and a total circuit current of 4.2 amps?

Answer: 1260 Watts

Question: Three lamps, with wattages of 100 watts, 250 watts and 60 watts, are connected on a circuit. What is the total power consumed by the circuit when all lamps are operating at the rated voltage?

Answer: 410 Watts

Question: Two heaters are connected on the same 120-volt circuit. If the heaters draw 5 amps of current each, how much total power is delivered to the heaters?

Answer: 1200 Watts

Question: Which formula will not be required to calculate the total circuit power in the circuit using the indirect method?

Answer: D. P(T) = E(T)^2 x I(T)
