An electric drill is rated at 720 Watts when operated at the main voltage of 240 V RMS. IN the operating manual the drill is described as double insulated.
Qs,
a What is the current passing through the drill motor when operating normally?
b What is the resistance of the drill motor when used normally?
c The drill is used by a tradesman on average for 50 mins a day for 220 days a year. The electricity company charges 12c per kilowatthour (no clue what this is). How much does it cost to run the drill for a year?
Please provide detailed explanations on how to solve each question as well as listing the rules needed to solve the problems
THANKS!!
