Answer:
24W used 24W balance
since the rate of consumption is not given
Explanation:
total power in battery =12*4=48Whr
this much energy is stored in your battery
if battery is used for 30min you consume half of its power , and thus 24W spend and 24W balance
considering the battery to be 100% efficient.

Potential difference =12 V(V)
Current=4 A(I)
Power consumed by the battery(P)=V x I
=12 x 4 =48 KW
Time=30 min=30/60=0.5 hrs
Electrical energy=P x t
=48 x 0.5
=24KWh
Current=4 A(I)
Power consumed by the battery(P)=V x I
=12 x 4 =48 KW
Time=30 min=30/60=0.5 hrs
Electrical energy=P x t
=48 x 0.5
=24KWh
