Determine whether the following statements are correct:
Electrical work depends on the flow of electric charge and voltage.
The basic unit for electrical work is the kilowatt hour.
With electrical work, there can be change in the energy of a body.
Energy conversion in electricity is always accompanied by heat.
In electric motors, all electrical work is converted into mechanical work.
When electric current flows through a resistor, all the electrical work done on the resistor is converted into heat. So, it heats up.
In filament lamps, most of the electrical part is converted to light.
