 The charging current of the 300AH battery will be 

(A) 30 A 

(B) 40 A

(C) 20 A

(D) 10 A


Ans: (A) 30 A 


Explanation: 

The charging current of the battery should be 10 % of the Ah ( Ampere hour) rating of the battery.


Here 

Battery rating = 300 Ah 


Charging current = 10 % of Battery ratting 

                            = (300 * 10 )/100

                            = 3000/100

                            = 30 A

This ampere is only for ideal case.

In actual case Due to some losses in battery charging current actual charging current is 30-32 A
