6 Nos Of 24 V, 400AH Batteries are connected in Parallel than Total Ah & Voltage & charging current of batteries ?

6 Nos Of 24 V, 400AH Batteries are connected in Parallel than Total  Ah & Voltage & charging current of batteries?

(A) 2400 Ah, 24 V & 240 A

(B) 2500 Ah, 24 V & 240 A

(C) 400 Ah, 144 V & 40 A

(D) 400 Ah, 24 V & 40 A

Ans:(A) 2400 Ah, 24 V & 240 A

Explanation:

Here Given that

Nos of batteries = 6 Nos

Battery voltage = 24 V

Battery Ah = 400 Ah

Required Data

Battery Total Ah & Voltage = ?

Battery Charging Current = ?

Here battery are connected in parallel 

so formula

I = I1 + I2 + I3 + I4 + I5 + I6

In Case of Battery parallel connection Battery Voltage remain same and summation of Batrry Ah are carried out.

I = 400 + 400 + 400 + 400 + 400 + 400

I = 2400 Ah

Here voltage remain same 

So Total Voltage = 24 V

Charging current of bettery is 10 % of AH rating of battery 

Here Ah rating of battery is 2400 Ah 

Charging current = (2400 * 10)/100

                            = 24000 / 100

                            = 240 A 

So final Ans is 2400 Ah, 24 V & 240 A
