Answer:
<em>a. q=450 c </em>
<em>b. E=675 J </em>
Explanation:
<u>Direct Current (DC) </u>
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
