An electric kettle is labelled "1500 W, 250 V". Assume that the resistance of its heating element remains constant.
a. (a) The kettle is connected to a 200V supply. Calculate the power it will consume at this voltage.
b. (b) Determine the current drawn from the 200V supply.
c. (c) At what supply voltage would the kettle consume exactly 1000W of power?
