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 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.
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).
Can different rating circuit breakers have the same short circuit characteristics?
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
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.
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 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.
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.
An open circuit results when a hot wire touches ground?
A short circuit is the term for hot touching ground. This can cause a breaker to trip which will then open the circuit.
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
