What voltage is required to supply a 20 amp load on a circuit with a resistance of 6 ohms?

To determine the voltage required to supply a 20 amp load with a resistance of 6 ohms, the application of Ohm's Law is essential. Ohm’s Law states that voltage (V) is equal to the current (I) multiplied by the resistance (R), represented by the formula: V = I × R.

By substituting the given values into this formula:

• Current (I) is 20 amps,

• Resistance (R) is 6 ohms.

Calculating gives:

V = 20 amps × 6 ohms = 120 volts.

Therefore, the required voltage to support a 20 amp load with a resistance of 6 ohms is indeed 120 volts. This demonstrates a direct relationship between voltage, current, and resistance, emphasizing the importance of understanding these concepts in electrical circuits.
