Two cells of e.m.f. 10 V & 15 V are connected in parallel to each other between points A & B. The cell of e.m.f. 10 V is ideal but the cell of e.m.f. 15 V has internal resistance 1 Ω Ω . The equivalent e.m.f. between A and B is:
A
V
B
not defined
C
15 V
D
10 V
Text Solution
Verified by ExpertsThe correct answer is:
D
For ideal, r → 0
E = 
E = 10 V
