Answer:
E =9525.6 J
Explanation:
Given that
Current ,I = 4.9 A
time ,t = 5.4 min
Voltage difference ,ΔV = 6 V
energy delivered by battery in time t is given as
E=V I t
where V is voltage, I is the current and t is the time.
now putting the values in above equation
E= 6 x 4.9 x 5.4 x 60 J ( 1 min = 60 s , 5.4 min = 5.4 x 60 s)
E =9525.6 J
Therefore the energy reduced will be 9525.6 J
