Each morning you stand up, eat breakfast and take a shower. Before you go into the bathroom, you turn the light on and after showering you plug in the hair dryer.
The light bulb has an power of 12 ampere and the hair dryer uses 2'200 Watt, both the light and the hair dryer have been on for 10 minutes.
How many kWh have you consumed by drying your hair while the light was turned on?
