Superposition

Question 1

What principle states that the voltage across (or current through) an element in a linear circuit is the algebraic sum of the voltages across (or currents through) that element due to each independent source acting alone.

Answer 1

Superposition

Question 2

In superposition, we consider one independent source at a time while all other independent sources are ___________.

Answer 2

turned off

Question 3

__________ sources are left intact because they are controlled by circuit variables.

Answer 3

Dependent

Question 4

Steps in Superposition principle:

1. Turn off all ____________ sources except one source. Find the output (voltage or current).

Answer 4

Independent

Question 5

Steps in Superposition principle:

2. Repeat step 1 for each of the other ___________ sources.

Answer 5

Independent

Question 6

Steps in Superposition principle:

3. Find the ______ _________ by adding algebraically all the contributions due to the independent sources.

Answer 6

Total contribution

Question 7

Superposition is based on ________.

Answer 7

Linearity

Question 8

It is not applicable to the effect on power due to each source, because the power ________ by a resistor depends on the square of the voltage or current.

Answer 8

absorbed

Question 9

If the ______ _______ is needed, the current through (or voltage across) the element must be calculated first using superposition.

Answer 9

Power value
