Difference Between Open Circuit and Short Circuit:

~~ A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. But Open Circuit is an electric circuit that has been broken, so that there is no complete path for current flow.

~~ In the case of short circuit model, the RF device will use the input impedance of the next stage as its load. In the case of open circuit, the device is isolated from the next stage, however, the signal still goes through.

~~ An open circuit is where there is no current flow ans voltage tends to infinity. A short circuit is where the voltage tends to zero and current tends to infinity.

~~ Short circuit is a circuit where the impedance is very low, close to zero ohms, causing a high current. This is often a fault condition. An open circuit is a circuit where the impedance is very high, close to infinity ohms, casuing no current.

How can I know to apply Open circuit and closed circuit in a circuit diagram.

Theory about effect of open and short circuit in simple circuit

let you have circuit with a load(Resistence). If you replace the load and place a normal copper wire it will become short circuit. By short circuit you only have current.
let you have circuit with a load(Resistence). If you remove the load and keep the ciruit end open. it will become open circuit. From open circuit you only have voltage.
