Answer:
Electric kettle heating element resistance may be determined using the following formula:
The formula for resistance is: R = V2 / P. (P)
Explanation:
The following equation may be used to get the resistance of the electric kettle, given its 3 kW (kilowatts) and 240 V ratings:
R = V² / P
R = (240) (240)
² / 3000 \sR = 19.2 Ω (ohms) (ohms)
Thus, the electric kettle's heating element has a resistance of 19.2.
The quantity of current that flows through the element during the operation of the kettle is directly proportional to its resistance value. If the resistance increases, the current decreases, and vice versa. As the resistance is low, much electricity will flow through the kettle's heating element whenever it is activated.
It's also important to know that the electric kettle's power rating (3 kW) reflects the efficiency with which the heating element transforms electrical energy into thermal energy. Hence, a more excellent power rating indicates a quicker rate for water to be heated in the kettle.
