Identify which of the following would be the most appropriate choice of fuse for a 1200W kettle operating on UK mains electricity (230V). A) 3A Fuse B) 5A Fuse C) 10A Fuse D) 13A Fuse

The answer is C) 10A Fuse.To calculate the current flowing to the kettle, you use the P=IV equation to work out that I=P/V. Putting P = 1200 and V = 230 into this equation gives I = 1200/230 = 5.217A. Theref...
