## HOMEWORK

For Friday 15th November,

Finish the question on POTENTIAL DIVIDER circuits in the ELECTRICITY BOOK. NB, these Questions are also given in the LOQ so you can answer them on paper and keep your notes up to date.

the OCTOBER ASSESSMENT, including where you went wrong and how you can correct this.

## homework for 9th Sept

Homework:

Section 9.1 and 9.2 of the Learning Outcome Questions

see the Electricity Section of the Website for the Draft version of these.

Put your name on them and hand them in to the Green Tray on Monday.

## Revision Questions

Thanks to those in North Ayrshire who provided these excellent questions for you to get your teeth into. I’ll post the answers as password protected to protect those students and staff who are given these for homework! They’re in the old order, so you’ll have to search through for the right section.

ENJOY!

Here is the topic song

Updated November 2019

Electricity 2017 Final word version of the Electricity Unit.

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.

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

#### 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

VOLTAGE divider circuits (2)

POTENTIAL DIVIDERS2

POTENTIAL DIVIDERS

VOLTAGE divider Q  Practice those horrible voltage divider questions with this pdf version of the document below. The answers are given for you to check. VOLTAGE divider Q

#### 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.
