Electricity

Preparing for the test

Welcome!

Plan for today

1. Recap of chapter 4 (probably quite long)

        > Conductors & Insulators

        > Voltage & Current

        > Series & Parallel

        > Power & Energy

2. Electricity sudokus 

Insulators and conductors

              Insulators                                                                   Conductors

Voltage and current

The electrical current is the amount of charge that passes through a device.

The voltage is the amount of energy that the charges carry.

How can we draw circuits?

We use symbols! These are some of the most important ones:

Wire

Battery

Light bulb ('lampje')

Voltmeter/ Ammeter 

Switch

LED

Series circuit

Parallel circuit

Electrical power

P is the electrical power in W

U is the voltage in V

I is the current in A

P=U⋅I

Electrical sudokus

You need to check each level before you continue to the next!

How to study for the test?

Make sure you understand the blue words

Do the Test Yourself for each paragraph

Make a lot of exercises!!!
