Flashcards in Circuits - the Basics Deck (7):
1

Do the paper flashcards on circuit symbols

They're in the study

2

Standard test circuit:
Describe the ammeter

1) Measures the current (in amps) flowing through the component
2) Must be placed in series
3) Can be put anywhere in series in the main circuit

3

Standard test circuit:
Describe the voltmeter

1) Measure the p.d (in volts) across the component
2) Must be placed in parallel around the component under test

4

Describe and DRAW the Standard test circuit

5

What is the Standard test circuit used for?

Testing components and for getting V-I graphs from them

6

Standard test circuit:
Which components are is series? Which means...

The ammeter, variable resistor and the component so they can be put in any order in the main circuit

7

What happens when you vary the variable resistor?

It alters the current flowing through the circuit
