VIRTUAL GROUND:-
1]If the non-inverting (+) terminal of OP-AMP is connected to ground, then due to the "virtual short" existing between the two input terminals, the inverting (-) terminal also be at ground potential. hence it is said to be as "virtual ground".
2]similarly if the inverting (-) terminal is connected to ground, then the non- inverting (+) terminal will be at "virtual ground" potential.
3]The concept of virtual ground has been used extensively for amplifier analysis, specially we use this concept in the inverting amplifier.
VIRTUAL SHORT:-
1] The input impedance (Ri) of an OP-AMP is ideally infinite. Hence current "I" flowing from one input terminal to the other will be zero.
2] Thus the voltage drop across Ri will be zero and both input terminals will be at the same potential. In other words they are virtually shorted to each other.
What else can I help you with?
What is shot circuit?
When there is a very current flow with virtual no voltage caused a hard wire short
How does a thermal overload control a circuit when the phase short to ground?
If you are describing a circuit breaker then its electromagnetic trip component will operate in the event of a line*-to-ground (*not 'phase'!) short circuit. The thermal overload component will only operate in the event of a sustained overload.
Is short to voltage the same as short to ground?
No, short to voltage and short to ground are not the same. A short to voltage occurs when a component is connected directly to a voltage source, bypassing the normal circuit path, which can lead to excessive current flow and potential damage. In contrast, a short to ground happens when a circuit connects directly to the ground reference point, potentially causing a fault condition that can also lead to damage. Both scenarios can be hazardous, but they affect circuits differently.
What is the two types of ground circuit?
1. direct ground circuit 2. virtually ground circuit
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
Why is your engine control fuse keep blowing?
There is an overload or short to ground in the circuit.There is an overload or short to ground in the circuit.
Reverse light fuse keeps blowing out?
Short to ground or overload in the circuit.Short to ground or overload in the circuit.
What type of failure might blow the fuses?
A dead short to ground or an overloaded circuit.A dead short to ground or an overloaded circuit.
The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is a Winding-To-Ground Short Circuit?
No
Why wiring short circuit?
A "hot" positive wire has made contact with ground = short circuit.
Why does your ecs fuse keep blowing?
There is either a short to ground or an over current condition in the circuit.There is either a short to ground or an over current condition in the circuit.
How do you generate short circuit current?
A short circuit occurs when the hot side of the supply comes in contact with ground.
What happens when any phase conected to ground?
You get a short circuit.
WHAT MAKES A CIRCUIT FAIL?
An open.A short to ground. Resistance.
What is shot circuit?
When there is a very current flow with virtual no voltage caused a hard wire short
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.
