How much current will flow in a circuit with a heater operating at 240 volts and a resistance of 28 ohms?

To determine the amount of current flowing in the circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, the voltage provided is 240 volts, and the resistance is 28 ohms.

Using the formula:

[ I = \frac{V}{R} ]

Substituting the given values:

[ I = \frac{240, \text{volts}}{28, \text{ohms}} ]

Calculating this gives:

[ I = 8.57, \text{A} ]

This calculation shows that the current flowing through the circuit is 8.57 amperes, confirming that this choice accurately reflects the proper application of Ohm's Law. Understanding how to apply this law is crucial in electrical work since it allows you to relate voltage, current, and resistance effectively, which is foundational knowledge in the field.
