## 1. Kirchhoff’s first law is also known as ?

1. Kirchhoff’s current law
2. Kirchhoff’s point law
3. Both (A) and (B)
4. None of the above

Memory: Kirchhoff’s Current Law Statement:

Kirchhoff’s current law states that, algebraic sum of all currents meeting at a point is zero or the algebraic sum of incoming currents towards a point is equal to the sum of outgoing current away from that point.

As shown below, ## 2. Kirchhoff’s voltage law deals with –

1. Junction current
2. IR drops
3. Battery emf
4. Both (B) and (C)

Memory: KVL is used to find out voltage drops across resistors and battery emf.

## 3. Kirchhoff’s second law is also known as ?

1. KVL
2. Mesh law
3. Both (A) and (B)
4. None of the above

Memory: No memory available.

## 4. Kirchhoff’s laws are modification of ?

1. Ohm’s law
2. Coulomb law
4. Lenz’s laws

Memory: No memory available.

## 5. In kirchhoff’s current law (KCL), the algebraic sum of all currents to and from a node will be ?

1. Positive
2. Negative
3. Zero
4. Infinite

Memory: No memory available.

## 6. Kirchhoff’s laws are not applicable to circuits containing –

1. Linear elements
2. Lumped parameters
3. Distributed parameters
4. Non-linear elements

Memory: A distributed parameter circuit is one that contains unlimited number of elements, eg. transmission line.

Such a situation, kirchhoff’s laws are not applicable.

## 7. In kirchhoff’s voltage law (KVL), the resistive drops due to flow of current in clockwise direction must be taken as –

1. Positive drops
2. Negative drops
3. Zero
4. None of the above

Memory: It must be taken positive, otherwise KVL won’t work.

## 8. According to, kirchhoff’s voltage law, the resistive drops due to flow of current in anti-clockwise direction must be taken as ?

1. Positive drops
2. Negative drops
3. Can’t be determine
4. None of the above

Memory: No memory available.

## 9. The above diagram shows KCL, what will be the correct equation of the below choices ?

1. I1 – I2 – I3 + I4 – I5 + I6 = 0
2. I1 + I2 + I3 – I4 – I5 – I6 = 0
3. I1 – I2 + I3 – I4 – I5 + I6 = 0
4. – I1 + I2 – I3 + I4 – I5 + I6 = 0

Memory: In KCL, All the incoming currents towards the node are taken as positive, while all outgoing currents from the node are taken as negative.

As shown below,  ## 10. In the above figure kirchhoff’s voltage law circuit is shown, what is the correct equation of the above circuit ?

1. E1 – E2 = R3 I2 + R4 I2 + R5 I1
2. E1 + E2 = -R3 I2 – R4 I2 + R5 I1
3. E1 – E2 = -R3 I2 – R4 I2 + R5 I1
4. E1 + E2 = -R3 I2 + R4 I2 – R5 I1
