2.4 understand that a current in a resistor results in the electrical transfer of energy and an increase in temperature, and how this can be used in a variety of domestic contexts
As a resistor slows down the movement of electrons, the kinetic energy that was moving them is converted into heat energy. This can be used, for example, in hair dryers or heaters.

ReplyDeleteThis is actually 2.5 now, not 2.4, 2.4 is about electrical heating in domestic appliances
ReplyDelete2.5 is about current x voltage = power u tism
Deleteit is actually 2.3
Deletenew spec thats why
Delete2.3 as of 2019

ReplyDeletethank you so much, this entire website has been one of the things that help me survive this year because I have a teacher that nobody in my class can understand so we basically have to teach ourselves the entire syllabus...
