A 6.0-V battery that can store 500.0 J. Of energy is connected to a resistor.How much charge must flow between the battery's terminals to completely drain the battery if it is fully charged? Assume that the voltage of the battery remains the same until it is totally drained.
A)83 C
B)0.010 C
C)3,000 C
D)0.07 C

Question

Quizplus · Accepted Answer

The energy stored in the battery (E) is given by:
E = VQ
where V is the voltage of the battery and Q is the amount of charge that flows between its terminals.

Rearranging the equation gives:
Q = E/V

Substituting the given values:
Q = 500.0 J / 6.0 V
Q = 83.3 C

Therefore, the amount of charge that must flow between the battery's terminals to completely drain the battery is 83 C. Therefore, the answer is A).
