Problem

A bicycle dynamo supplies a potential difference of 6 V6\,\text{V} to the headlamp, and a current of 200 mA200\,\text{mA} flows through the filament. (i) Calculate the electrical power developed in the lamp. (ii) The cyclist keeps the lamp on continuously for 10 min10\,\text{min}. Determine the total electrical energy converted by the lamp in this time.
