How to solve superposition circuit with two sources?
There are two sources, so we need to turn them off one by one and calculate associated values. Two announcements before we start! First, a PDF sheet of this problem with the solution and side space for notes can be downloaded below. Second, you may watch solving this problem on the video posted below.
When is a short circuit replaced by an open circuit?
While considering the effect of individual sources, other sources must be non-operative such that they are replaced by their internal resistance. If the sources are ideal they are replaced by a short circuit or open circuit for voltage source and current source respectively.
Can a circuit be solved with a zero current?
Zero current means no way for current to pass and that is possible with an open circuit. To continue solving the circuit with the Superposition method, we should make the voltage source zero and find the contribution of the current source on .
How to find the total resistance of a short circuit?
So, the current supplied by the 48V source is 6.86 Amperes. Now consider the 24V source alone and replace 48 V source by a short circuit. Now find the total resistance of the circuit and by find the total current supplied by the source.
Which is the result of the superposition theorem?
The superposition theorem states that the response (voltage or current) in any branch of a linear circuit which has more than one independent source equals the algebraic sum of the responses caused by each independent source acting alone, while all other independent sources are turned off (made zero).
Is the power equation not applicable to superposition?
Since the power equation is not linear, it is not applicable for power calculations. Not applicable to a network containing time-varying resistors. Applications of Superposition Theorem Any circuit can be converted into Thevenin equivalent or Norton equivalent using this theorem.
