To determine the applied circuit voltage in a parallel circuit with a given total current and resistance, you can use Ohm’s Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). In this scenario, you know the total current (10 amps) flowing in the circuit and the equivalent resistance for the entire parallel setup (20 Ohms).

Applying Ohm’s Law:

[ V = I \times R ]

Substituting the values into the equation:

[ V = 10 , \text{amps} \times 20 , \text{Ohms} = 200 , \text{volts} ]

Thus, the applied circuit voltage in this parallel circuit is 200 volts. This aligns with the characteristics of parallel circuits, where the voltage across all components remains the same as the source voltage regardless of the individual branch resistances. Therefore, the correct calculation leads to the conclusion that the applied circuit voltage is indeed 200 volts.
