RELATION BETWEEN POTENTIAL DIFFERENCE AND ELECTRICS CURRENT

Objective

:

searching relation between current potentialdifference at one particular network

Apparatus and material a. c. d. e. f. g.

strength

and

:

4 battery Switch Wire Volt meter Ammeter Bulb

Activity Step

:

1. Design the apparatus according to figure following as :

2. Turn on switch till current flow in circuit. Then observed and read showed by scale voltmeter and ammeter. Paying attention way of reading voltmeter and ammeter. Note its result at tables of observation!

3. Do activity 2 for different tension by adding battery alternately ( 2, 3 and 4 battery )

Tables of result observe:

Amount of the source of Tension.

No

Potential difference (V) Unit of volt

1

1 battery

2

2 battery

3

3 battery

4

4 battery

Electric current( I ) Unit of Ampere

4. From result of activity, Depicting relation graph between potential difference ( V ) powerfully current ( I ) pursuant to tables of your perception ! Relation what is all of you obtain; get from graph !

IV(A) (volt)

Analysis 1. Basically to graph and table above, how change of potential different value with electric current?.........................................................................................................................................
