Question

A circuit consists of a battery connected to three resistors (60 , 25 , and 160 ) in parallel. The total current through the resistors is 1.9 .

Part A
Find the emf of the battery.
Express your answer using two significant figures. (in V)

Part B
Find the current through 60 resistor.
Express your answer using two significant figures. (in A)

Part C
Find the current through 25 resistor.
Express your answer using two significant figures. (in A)

Part D
Find the current through 160 resistor.
Express your answer using two significant figures. (in A)

Explanation / Answer

a)Let V be the emf.

V/60+V/25+V/160=1.9

V=30.2V

b)I60=V/60=0.503A

c)I25=V/25=1.208A

d)I160=V/160=0.189A
