Objective Of Assignment :

To learn how to connect the component become acomplete circuit.

To apply how many connection can be done withspecific and limited component.To identify connection can be used in circuitTo prove the ohms law and kirchoff law in circuit.

Question 1 :Using only two(2) betteries, two(2) light bulbs andnot more then four(4) wire:

i) identify how both light bulbs can be made toglow.

Component are using :

1. Two batteries 9 V each

2. Two bulbs3. Four wires4. Ammeter5. Voltmeter

Connection Made Both BulbsGlow

1) Two bulbs and two batteries connect In seriesconnection

2) Two batteries connect in parallel and twobulbs connect in series connection.

3) Two batteries connect in series and two bulbsconnect in parallel connection

4) Two batteries connect in parallel and twobulbs connect in parallel connection.

Question 1 :Using only two(2) betteries, two(2)

light bulbs and not more then four(4) wire:

ii) identify how light bulbs can bemade to glow at their brightest


11/18

To made both bulbs brighter1. Their connection among batteries and bulbs2. Source of voltage are higher3. Low of resistance exist in circuit.

4. Higher value of total current.

* Bulbs connect in parallel and batteries connect in seriesconnection is most brighter glow of both bulbs due of high value of

total voltage and total current among others

Question 1(iii) the different

between question (i) and (ii) we need create and builda circuit that can makebulbs glow.

we need select amongthose circuits which onemade bulbs glow brightly and identify how it madebrightest.

Question 1(iv): Compare question (i)and (ii) in term of current, potentialdifference and resistance.
