According to Ohm's law, what voltage is required to push 1 amp of current through 1 ohm of resistance?

Explanation:
Ohm's law states that voltage equals current times resistance (V = I × R). If you want 1 amp through 1 ohm, you multiply: 1 A × 1 Ω = 1 V. So the voltage across that resistance needs to be 1 volt. If you used a higher voltage, you’d get a proportionally higher current (5 volts would push 5 A, 10 volts would push 10 A). The phrase “source voltage” isn’t a fixed value; you determine the needed voltage from the desired current and the given resistance.
