Question
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;
Options
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 
Solution
Eeq = 
Eeq = KE
.........upto 
erq = 
For maximum power req = R ⇒
= R ⇒ K = 
Pmax =
Pmax =
⇒ Pmax = 
Eeq = KE
.........upto erq = For maximum power req = R ⇒
= R ⇒ K = Pmax =
Pmax =
⇒ Pmax = Create a free account to view solution
