Answer :
Final answer:
Plug outlets are designed for specific voltages such as 110 V or 220 V, with distinct shapes to match their intended voltage. Appliances like a dryer typically use a 220 V outlet and draw considerably less power if rewired to fit into a 110 V outlet, due to the quadratic relationship between voltage and power.
Explanation:
the types of plug outlets that can handle either 110-volt or 220-volt electrical systems. In general, electrical receptacles are designed for a specific voltage and have differing shapes to prevent incorrect usage. Most home outlets in the United States are 110 V, while higher-powered appliances, such as electric stoves, air conditioners, and washers and dryers, usually require 220 V and have distinct receptacles accordingly.
If a dryer, which typically uses a 220 V outlet and normally draws 200 watts (W) when powered correctly, is altered to be plugged into a 110 V receptacle, the power it actually draws will change. The power dissipated by a resistor, which includes the heating element in a dryer, can be expressed as P = (V2)/R, where P is power, V is voltage, and R is resistance.
Given that the heating element is designed for 220 V use, if you plug it into a 110 V outlet, the voltage is halved, and thus the power draw will also change according to the relationship above. However, without the specific resistance value of the heating element, we cannot calculate the exact power draw at 110 V. Nonetheless, the important takeaway is that the power draw will be significantly less than 200 W at 110 V because of the quadratic relationship between voltage and power.
