C)8 volts.
D)none of the above.

Question

Quizplus · Accepted Answer

From Ohm's Law, we know that voltage (V) is equal to the product of the current (I) and resistance (R): V = IR.

Using the given values, we can calculate the voltage of the battery: V = 2 A x 4 Ω = 8 volts.

Therefore, the correct answer is C) 8 volts.
