In circuit equivalence, voltage and current sources are respectively equated to short and open ckt because of the very nature of them. A voltage source has zero internal resistance and current source has infinite internal resistance hence their equivalents:-)
What else can I help you with?
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
How are the capacitors treated in the dc equivalent circuit of an amplifier?
In dc equivalent circuit of an amplifier all capacitors are replaced by open circuit because capacitor block dc. As , Xc=1/2πfC We know that that frequency of dc is zero so Xc will infinite so we replace all capacitors with open circuit.
What is the difference in an open circuit and a short circuit?
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
When the current will be short and open circuited?
Open circuit has no current, so does that mean any resistor in series with it, has no current ,so it can be ignored for analysis( v=ir so 0 current means 0 V) for finding lets say the Thevenin equivalent.? Now for Short circuit, do we ignore a resistor in series with the short, because current will take path of least resistance and ignore that resistor? Also can short circuit have voltage through it ?
What are the safety features available in a breaker?
To detect and open the circuit if a thermal overload is present and to detect and open the circuit if a short circuit caused by a magnetic increase of flux in the circuit.
If a fuse melts does it create an open circuit a closed circuit or a short circuit?
If a fuse melts, it creates an OPEN circuit, meaning that no current flows in the wires because it is no longer a complete circuit.
What is more dangerous a short circuit or an open circuit?
A short circuit is generally more dangerous than an open circuit because it allows a current to flow through an unintended path, leading to overheating, fires, and potential damage to electrical components. An open circuit, on the other hand, simply means that the circuit is incomplete and no current can flow, which may simply result in a non-functioning device.
What is infinity on a multimeter?
If is being used as an ohmmeter it usually means an open circuit. A switch may be open, or a wire is broken (not a short circuit)
