hi here is the question
A 60 watt light bulb is left swithed on for 10 hours. If the light bulb is 15% effcient, calculate the amount of light energy produced in that time. what is the total energy consumption of the light bulb in this time.
so i need to find work done right so is that power divided by time to get the energy and then find 15% of that am i right i am bathed by this.
