Questions
In circuit shown below, the resistances are given in ohms and the battery is assumed ideal with emf equal to 3 volt. The voltage across the resistance R4 is
detailed solution
Correct option is A
∴ Total current through battery, i=375i1 =i2 = 375 ×2 = 3150current through R4 = 3150 × 630 +60=3150 × 6090=2150 AV4 =i4 × R4 = 2150 × 30=25V=0.4 VTalk to our academic expert!
