If a circuit has 200 ohms of resistance and 50 volts are applied, what is the current?

To find the current in a circuit, Ohm's Law is applied, which states that current (I) is equal to the voltage (V) divided by the resistance (R). In this scenario, the voltage is 50 volts and the resistance is 200 ohms. Using the formula:

I = V / R

we can substitute the given values:

I = 50 volts / 200 ohms

Calculating this gives:

I = 0.25 A

Therefore, the current flowing through the circuit is 0.25 amperes. This calculation aligns with the principles of electricity, where increasing resistance results in a decrease in current for a fixed voltage.
