Question

Using the principle of superposition, find the current flowing through the 12 kresistor, connected between the terminals aand b, of the below given circuit.

Answer 1

Answer:

The principle of superposition is another name for the additivity property of Linearity:

f(x_1 + x_2) = f(x_1) + f(x_2)f(x

1

+x

2

)=f(x

1

)+f(x

2

)f, left parenthesis, x, start subscript, 1, end subscript, plus, x, start subscript, 2, end subscript, right parenthesis, equals, f, left parenthesis, x, start subscript, 1, end subscript, right parenthesis, plus, f, left parenthesis, x, start subscript, 2, end subscript, right parenthesis

To solve a circuit using superposition, the first step is to turn off or suppress all but one input.

To suppress a voltage source, replace it with a short circuit.

To suppress a current source, replace it with an open circuit.

Then you analyze the resulting simpler circuits. Repeat for all inputs.

The final result is the sum of individual results.
