N cells each of e.m.f. E & identical resistance r are grouped into sets of K cells connected in series. The (N/K) sets are connected in parallel to a load of resistance R, then;
A
Maximum power is delivered to the load if K = 
.
.
B
Maximum power is delivered to the load if K = 
C
Maximum power delivered to the load is 
D
Maximum power delivered to the load is 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, d)
E eq = 
E eq = KE, 
........ upto 
r eq = 
For maximum power r eq = R
⇒ 
= R
⇒ K = 
maximum power = P max = I 2 R = 
= 
= 
= 
=
