Current Electricity and Electrical InstrumentHard
Question
The current in the given circuit is :
Options
A.0.3amp
B.0.4amp
C.0.1amp
D.0.2amp
Solution
Two batteries are joined with opposite polarity so, total e.m f. = 5 - 2 = 3V
Total resistance = 10 + 20 = 3
Current =
= 0.1A
Total resistance = 10 + 20 = 3
Current =
= 0.1ACreate a free account to view solution
