(a) What is the average power consumption in watts of an appliance that uses 5.00 kW ? h of energy per day? (b) How many joules of energy does this appliance consume in a year?
Step-by-step solution Step 1 of 2 (a) The total energy consumed by the electric clock in a day is . As one is equivalent to Therefore, The total time in on day is The relation between the power of a device and energy consumed over a time period is Substitute the values of total time in on day is and energy consumed in the above equation The average power consumption in watts is
