ELECTRICITY from 2017

Updated November 2019

Electricity 2017 Final word version of the Electricity Unit.

Electricity 2017 Final  pdf version.

The booklet is large as it contains lots of questions for you to practice, practicals for you to complete and notes.

They are large notes so that you ought to be able to work your way through whether you are in class or away at college etc.

Please return your copy to the faculty on 30th April 2020!

The section numbers are linked to the compendium with all the things to cover in National 5 Physics.

Thanks to the person on GUZLED who shared these. I’ve redone them so they don’t lose their formatting.

Ohm’s Law

Components

resistor network Try this when you think you have got to grips with resistances in series and parallel.

AC_DC[1] This is a powerpoint presentation that someone passed to be in the days of SG. It covers AC and DC traces

Voltage (2)

Voltage Analogy

Voltage Dividers

VOLTAGE DIVIDER FORMULAE The formula sheet for voltage dividers

Feeling brave- this isn’t as hard as it looks, but you can impress your friends and family.

Other notes

Mains- Electricity in the home

Here are some additional notes that might help as you go through the materials. Check out the post on using your calculators to measure resistance (I’ll add the link here when I’ve found the post!)

Ring main   Based on the SG course notes and not really in the N5 course, but it might give a little background to why when calculating the fuse rating for an appliance you use 240V and not the 230 V as stated.

Older Notes

EE1 – Electricity LOCKERBIE The old electricity notes (based on a colleagues work- thank you and I’ll find out who you are), these will be superceded when the document above is completed.

Elect & elect D&G Prob Book no answers These are some great little questions by Mr Belford from Dumfries Academy, but some of the numbers are a little bit fictional!

HOMEWORK for NOVEMBER

If you work with up to 2 other people say who you are working with. If you are copying from two other people that makes a mockery of doing this. If you know about an absence you can get ahead. If you’re sick you can catch up! Excuses not accepted.

Week 1: 14/11/17

On the Past paper section of this site, open the document from the N5 exam paper table  that says “Read this First”.  Enlarge the document and skim read the boring pages at the beginning. Then take each response to each area and decide how you would mark it. Give your reasons. Compare to the Instructions to Markers. Hand this in on Tues 14th November.
