1

-(a)-

Ammeter

2

-{___}-

Resistor

3

-([___])- with 2 arrows shooting out from the left

LDR - Light Dependent Resistor

4

-(I>l)- with 2 arrows shooting out from the right

LED - Light Emitting Diode

5

-(I>l)-

Diode

6

-[/]- with an arrow in the middle going upwards

Variable resistor

7

what is the equation for Resistance?

Resistance (Ohms) = Potential differnce (Volts) / Current (Amps)

8

what is each symbol for resistor, potential difference, and current?

V - potential difference
I - current
R - resistance

9

what is the equation for Potential difference?

Potential difference = Current x Resistance

10

What is an independent variable?

Something you change

11

What is a dependent variable?

Measurement, thing you will measure

12

What is a control variable?

Something you keep to make the test fair

13

What are the two different circuits?

series circuit and parallel circuit

14

what is a disadvantage of a series circuit?

if one of the bulbs break then the entire circuit doesn't work.

15

-(x)-

bulb

16

-(v)-

voltmeter

17

-(m)-

Motor

18

--I i--

cell

19

-I i- -I i

battery

20

what is a parallel circuit?

different components connected to different parts of a wire, usually having wires parallel to one another.

21

why is a parallel circuit better than a series?

If in a parallel circuit one of the components break then the rest of the components on the other wire will carry on working, however, they won't produce as much energy as if both of the components were working on both wires.

22

The electrical conductor has what type of resistance?

Low resistance

23

The electrical insulator has what type of resistance?

High resistance
