Final answer:
The voltage can be calculated using Ohm's Law: V = I * R. In this case, the voltage is 5000 V.
Step-by-step explanation:
The voltage can be calculated using Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). In this case, the current is 20 amperes (A) and the resistance is 250 ohms (Ω), so the voltage can be calculated as V = I * R = 20 A * 250 Ω = 5000 V.
