To be honest it’s been a tough week…2 days of learning about electrical circuits, a module that’s perhaps a little dry for us but made bearable with some hands on circuit making and unique teaching methods.
So I’m going to get technical for a second or two (helps me remember by ‘regurgitating’ it):
We learnt that a circuit is like a pathway made of wires that electrons can flow through. A power source gives the force (voltage) that makes the electrons move. When the electrons get to a device like a light bulb they give it the power to make it work. Important to remember the word “circuit” sounds like “circle,” and a circuit needs to be circular to work. The wires have to go from the power source to the device and back again, so that the electrons can go out and come back.
Finally, many circuits have a switch so that they can be turned on and off. When the switch is off, it makes a gap in the circuit and the electrons are not able to flow around. When the switch is turned on, it closes the gap and the electricity is able to move and make the device work.
A week full of reading about techy stuff, and repetition…now, the challenge of retaining it all over the weekend before Monday’s exam!!
