If a circuit uses a 50-ohm resistor and supports 2 amps of current, what is the voltage across this circuit?

To determine the voltage across the circuit, Ohm's Law can be applied, which states that Voltage (V) is equal to the Current (I) multiplied by the Resistance (R). In this scenario, the resistance is 50 ohms, and the current is 2 amps.

Using the formula:

V = I × R

Substituting the known values:

V = 2 amps × 50 ohms = 100 volts

This calculation confirms that when a circuit has a resistance of 50 ohms and carries a current of 2 amps, the voltage across the circuit is indeed 100 volts. This result is grounded in the principles of electrical circuits, illustrating how voltage, current, and resistance interrelate according to Ohm's Law.
