Home » Electric Circuits » Electric circuits miscellaneous » Question

Five cells are connected in series in a row and then four such rows are connected in parallel to feed the current to a resistive load of 1.25 Ω . Each cell has emf of 1.5 V with internal resistance of 0.2 Ω . The current through the load will be _____ .

1. 1 A
2. 5 A
3. 15 A
4. None of the above

Correct Option: B

R_eq =	5 × 0.2	= 0.25
	4

I =	5 . E	=	5 × 1.5	= 5 A
	R_L + R_eq		1.25 + 0.25
