In a parallel circuit with a total resistance of 1.5 ohms and a total current of 10 amps, what is the total voltage?

To determine the total voltage in a parallel circuit, you can use Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). In this case, you're given the total current is 10 amps and the total resistance is 1.5 ohms.

Using the formula:

V = I × R

you can substitute in the values:

V = 10 amps × 1.5 ohms

Calculating this gives you:

V = 15 volts.

This result shows that the total voltage across the circuit is 15 volts, which corresponds to the correct answer.

Understanding this calculation helps in recognizing how voltage behaves in a parallel circuit where it remains the same across all components, while the total current is the sum of the currents through each path and total resistance is calculated differently than in series circuits.
