Home » Power Calculations » 15 » b Each of 9 resistors in a circuit is dissipating 4 watt. If the circuit operates from a 12 volt supply, the total current flowing in the circuit is: a. 48 ampere b. c. 9 ampere d. 3 ampere Your answer "b" is not correct. "d" is the right answer. Total power = 9 x 4 = 36 watts. P = E x I therefore I = P / E I = 36 / 12 = 3 amperes. Next |
