Question

23) In a series circuit consisting of 3 resistors of
45 ohms each and a 50-V source what is the
approximate amount of beat produced ?
(a) 16.6 W
(b) 18.5 W
(c) 135 W
(d) 150 W​

Answer 1

Answer:

(B)

Explanation:

POWER=V^2/R

RESISTANCE ARE CONNECTED IN SERIES,

THEREFORE, R=45+45+45

R=135ohm

P=50^2/135

=2500/135

Power =18.51watt
