Calculating Power and Fuses _ GCSE Physics

The video tutorial explains the concept of power, measured in watts, and how it relates to energy transfer over time. It provides methods to calculate power using energy in joules and time in seconds, as well as using current and voltage. The role of fuses in protecting electrical appliances from surges is discussed, along with guidance on selecting the appropriate fuse based on current flow and appliance specifications.

How do you determine the best fuse to use for an appliance?

What current flows through a 1.15 kilowatt electric fire with a voltage of 230?
