To Explain: The differences between given conditions.
Explanation of Solution
Introduction:When the compressor in a refrigerator turns ON, there is a spike in the current draw. It is usually referred to as a start-up draw or inrush.
The light will be dim because limited numbers of electrons can flow through the wire, and also, the resistance to the flow isvery low in motor windings. So, the most of electrons will flow through the motor.
In the second situation, heater will draw constant current. Also, it will remain high as the while it is turned ON.
So, these high current draw conditionscause lights on the same system to dim as they are being deprived of their normal current/ voltage.
Conclusion: The refrigerator causes a drain and also,draws up the electricity.
