DEVELOPMENT From what you now evidenced, explored, explained and analysed is there anything you could improve regardless of if

it is a good or bad point.

POINT Looking at a single aspect of a product (something it has to do).This generates the starting point.

EVIDENCE &

EXPLOREYou now need to use either: Prior Knowledge, Experience,

Research or Ask a friend why the point is important.

EXPLAIN Now with what you have found explain in detail using Who, What, Why, When, How or Because your point.

ANALYSE With your point now explained analyse and express your opinion whether it is good or bad.

Electronics Theory

Voltage is the electromotive force ( _ _ _ ) that exists across theterminals of a battery. It is also known as potential difference( _ _ ).

It is measured in _ _ _ _ s (V) and designated with the letter _.

Current is the rate of flow of electrical _ _ _ _ _ _ .It is measured in _ _ ­ _ _ _ _ s (A) and designated with the letter _.

Power is the rate at which _ _ _ _ is done.It is measured in _ _ _ _ s (W) and designated with the letter _.

P = x

Resistance limits the current in a circuit.

It is measured in _ _ _ s () and designated with the letter _.

Ohm’s Law is the relationship between voltage, _ _ _ _ _ _ _ and resistance.

To find out the voltage use: V = x

To find out the current use: I = ____

To find out the resistance use: R = ____
