7. Consider the same heater in Question 6. We try to protect the system against high currents using a fuse. What should be the current rating of the fuse if the household total current is 10A without the heater? (Assume that you can select from the standard ratings of 5, 10, 15, 20 and 25 A!)

I am asking question 7, but it is related to question 6.

6. An electric heater can be modelled as a resistor. In Turkey heaters are designed and sold for 220V mains. Let us connect an electric heater to a 220V plug. The total power of the heater is 2kW. What is the current through the heater? If the heater is used in a country, where the mains voltage is 110V, what power is dissipated on the heater? 7. Consider the same heater in Question 6. We try to protect the system against high currents using a fuse. What should be the current rating of the fuse if the household total current is 10A without the heater? (Assume that you can select from the standard ratings of 5, 10, 15, 20 and 25 A!)
