Question

Which of the following statement(s) is/are incorrect for the selection of lumped circuit elements?

A. The rate of change of the magnetic flux associated with any closed loop outside an element must be zero at every instance.

B. Total time inside the element variable charge at every instance.

C. The signal time scales in the circuit must be much greater than the transmission delay of the electromagnetic waves.

1. only B
2. both B and C
3. only C
4. none of the given options

Answer 1

Correct Answer - Option 4 : none of the given options

Lumped Network:

• If the network element can be separated physically from each other, then they are called a lumped network.
• Lumped means a case similar to combining all the parameters and considering it as a single unit.
• Lumped systems are those systems in which electrical properties like R, L, C, etc. are assumed to be located on a small space of the circuit.
• These systems are applicable to low-frequency applications.

 

Distributed Network:

• If the network element such as resistance, capacitance, and inductance are not physically separated, then it is called a Distributed network.
• Distributed systems assume that the electrical properties R, L, C, etc. are distributed across the entire circuit.
• These systems are applicable for high (microwave) frequency applications.
