Norton's Theorem

Question 1

States that a linear two-terminal circuit can be replaced by an equivalent circuit consisting of a current source (I_N) in parallel with a resistor (R_N), where I_N is the short-circuit current through the terminals and R_N is the input or equivalent resistance at the terminals when the independent sources are turned off.

Answer 1

Norton’s Theorem

Question 2

Formula: We find R_N the same way we find R_TH.

Answer 2

R_N = R_TH

Question 3

In what year was Norton’s Theorem developed?

Answer 3

1926

Question 4

How many years was Norton’s Theorem proposed after Thevenin published his theorem?

Answer 4

43 years

Question 5

He is an American engineer at Bell Telephone Laboratories, who proposed the Norton’s Theorem.

Answer 5

Edward Lawry Norton

Question 6

Formula: The relationship between Norton’s and Thevenin’s Theorems:

Answer 6

I_N = V_TH/R_TH

Question 7

Source transformation is often called as what?

Answer 7

Thevenin-Norton Transformation

Question 8

To find the Thevenin or Norton equivalent circuit requires that we find:

The ________ ________ across terminals a and b

Answer 8

open-circuit voltage (V_oc)

Question 9

To find the Thevenin or Norton equivalent circuit requires that we find:

The ________ ________ at terminals a and b

Answer 9

short-circuit current (I_sc)

Question 10

To find the Thevenin or Norton equivalent circuit requires that we find:

The ________ or ________ _____________ at terminals a and b when all independent sources are turned off.

Answer 10

equivalent or input resistance
