THEORY:

I) Kirchhoff's current law (KCL): It states that the total algebraic total of current meeting on the junction is definitely zero. This kind of law is dependent on the rule of conservation of fees.

KCL by junction " O”

I1+ I2+ I3+ I4 - I-5 - I6 =0

Therefore , I1+ I2+ I3+ I4 = I5+I6

CIRCUIT DIAGRAM:

PROCEDURE:

i) Connect the circuit. As shown in circuit diagram.

ii) Start the power supply.

iii) Notice the examining of ammeter

STATEMENT TABLE:

I2 (A)

I3 (A)

I3 (A)

calculated

I3 = I2+I1

CALCULATION OF CURRENT " I3”

I3 = I2+I1

RESULT:

Add the examining of ammeter 1(A1) & ammeter 2(A2) and it will be equal to browsing of ammeter 3(A3) I3 = I2+I1

KCL is confirmed.

PRECAUTION:

i) All connection should be limited.

ii) Prior to connecting the instruments verify their actually zero reading. iii) The port of the level of resistance should be effectively connected.

ii) Kirchhoff's voltage law (KVL):

It claims that the algebraic sum of voltage by using a closed loop is usually zero. This law is dependent on the theory of conservation of energy,

Exactly where, is the department voltage of close way.

CIRCUIT PICTURE:

PROCEDURE:

iv) Connect the circuit. Because shown in circuit plan.

v) Switch on the power source

vi) Take note the browsing of voltmeter. V1, A HUGE SELECTION OF, V3 (with polarity)
