Source Transformation

Question 1

The process of replacing a voltage source (Vs) in series with a resistor (R) by a current source (Is) in parallel with a resistor (R), or vice versa

Answer 1

Source Transformation

Question 2

If the sources are turned off, the equivalent resistance at terminals a-b in both circuits is ____.

Answer 2

R or Resistance

Question 3

When terminals a-b are short-circuited, the short-circuit current flowing from a to b is _______ in the circuit on the LEFT-HAND SIDE.

Answer 3

Isc = Vs/R

Question 4

When terminals a-b are short-circuited, the short-circuit current flowing from a to b is _______ in the circuit on the RIGHT-HAND SIDE.

Answer 4

Isc = Is

Question 5

The formula for the value of the Voltage Source (Vs).

Answer 5

Vs = IsR

Question 6

The formula for the value of the Current Source (Is).

Answer 6

Is = Vs/R

Question 7

Source transformation is NOT possible when _______.

Answer 7

R = 0

Answer 10

-on the top, + on the bottom

Question 11

When a current source is given (Independent or Dependent) with the current direction going UPWARDS, what is the equivalent voltage source?

Answer 11
