In the circuit shown, the current through the 4 
resistor is 1 amp when the points 
and 
are connected to a 
. voltage source. The potential difference between the points 
and 
is
Text Solution
Verified by ExpertsThe correct answer is:
B
As the P.D. between 
and 
(in parallel), are the same,
P.D. across points 
and 
Current in 
across 1 
volt
across 1 
volt.
