Arechargeable battery is capable of delivering a current of 0.25 a for 1800 s at a potential difference of 1.5 v.
calculate :
a. the total charge the battery is capable of delivering without being recharged,
b. the energy transferred from the battery as a result of delivering the charge calculated in part a

a. q=450 c

b. E=675 J

Explanation:

Direct Current (DC)

It's the flow of electric charges in one direction driven by a constant voltage circuit. The intensity of the current flow is computed as

Where q is the constant flow of charge in time t

The energy of an element providing Voltage V, current I during a time t is

a. The charge can be computed by solving the first equation for q

b. The energy transferred by the battery is
