If a circuit carries a current of 70 amps (A) with a resistance of 12 Ohms, what is the voltage (V) in the circuit?

To determine the voltage in the circuit, you can apply Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R). The formula can be written as:

V = I × R

In this scenario, the current (I) is given as 70 amps, and the resistance (R) is given as 12 ohms. Plugging these values into the formula, you would calculate:

V = 70 A × 12 Ω = 840 V

Thus, the voltage in the circuit is 840 volts. This calculation demonstrates the direct relationship between current, resistance, and voltage in an electrical circuit as defined by Ohm's Law, showing how an increase in either current or resistance results in a proportional increase in voltage.
