Five Important Points

Question 1

1. What is this very basic circuit used for?

Answer 1

Testing components and for getting I-V graphs for them

Question 2

2. What are the component, ammeter and variable resistor all in and what does this mean?

Answer 2

All in series, which means they can be put in any order in the main circuit

Question 3

3. What happens as you vary the variable resistors

Answer 3

It alters the current flowing through the circuit

Question 4

4. What does this allow you to do?

Answer 4

Take several pairs of readings from the ammeter and voltmeter
