What is the current through the 22 ohm heating element in a parallel circuit with a 220 volt source?

To determine the current through a 22-ohm heating element connected to a 220-volt source in a parallel circuit, you'll use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula can be expressed as:

I = V / R

In this case, the voltage (V) is 220 volts, and the resistance (R) of the heating element is 22 ohms. Substituting these values into the formula gives:

I = 220 volts / 22 ohms = 10 amps

This calculation shows that the current flowing through the 22-ohm heating element is 10 amps, making this the correct answer.

Understanding this concept is crucial, particularly in parallel circuits, as the voltage remains the same across all components, and the current can be calculated for each component independently using the same method.
