A 20 V battery is having a capacity of 4000 Ah. How long will it be able to drive a 950 W split ac unit? Assume battery power remains constant.

Step 1

Although,

A 4000 Ah battery on full charge will provide electrical energy for 4000 hours if circuit draws 1 amp current,

Step 2

But it is given that

Power rating of sink is 950 W and voltage of battery is 20V, therefore current drawn by the sink is

Current=power/vo...
