जे लोक सध्या कॉलेज मध्ये असतील अश्या लोकांनी preparation सोबत आपली कॉलेज लाईफ पण एन्जॉय करा जास्तीत जास्त वेळ मित्रांबरोबर spend करा एक चांगला healthy Circle तयार करा जे lifetime तुमच्या सोबत राहील!! पुस्तकी ज्ञान तुम्हाला नोकरी तर देईल पण लाईफ चे skill तुम्हाला कॉलेज कट्ट्या वर चांगल्या मित्रांसोबत च भेटतील. काही क्षण असतात आयुष्या मध्ये जिथे कोणी कामाला येत नाही तिथे आपले जवळचे मित्र कामाला येतात आणि चांगले मित्र हे फक्त कॉलेज time पर्यंत च भेटू शकतात नंतर फक्त collegue बनतील jealousy, competition ह्या गोष्टी मुळे कॉलेज लाईफ नंतर चांगले मित्र भेटणे कठीण च आहे. त्यामुळे दोन तीन हिरे आपल्या सोबत नेहमीच पाहिजेत ज्यांना आपण हक्काने हाक देऊ शकू. स्वार्थी जगामध्ये निस्वार्थ पणे साथ देणारे मित्र पाहिजेच❤️

Drawbacks or disadvantages of Solid State Relay
Following are the drawbacks or disadvantages of Solid State Relay:
➨It's cost is very high.
➨It is bound by specific current/voltage characteristics.
➨There is fixed value voltage drop on output due to internal impedance. Hence it is less efficient. This is negligible for high switching voltage operation.
➨There is leakage current at the output even if relay is in OFF mode.
➨It generates waste heat during ON mode. This is proportional to voltage drop.
➨It is triggered by brief voltage spikes on the input side unlike electromagnetic relay.
➨It is more vulnerable to surges and spikes in the current which is switched on output side unlike EM relay.
Benefits or advantages of Solid State Relay
Following are the benefits or advantages of Solid State Relay:
➨It offers very fast response usually about 1µs ON and 0.5 µs OFF.
➨It has very high life time.
➨It is smaller in size.
➨There are no physical moving parts involved in the design of solid state relay. Hence there is no mechanical noise. Moreover there will be no contact bounce and clean output signal is available.
➨It offers low power consumption due to less current requirement (5mA at 5VDC) .
➨It is highly durable.
➨There are no coils in the design which can introduce back EMF into the circuitry.
➨It is insensitive to vibration.
➨As there is complete internal separation between input and output terminals, it can be used to switch high voltages.
➨Some variants can work as low as 1.5V DC unlike Electromagnetic relay which requires at least 3V DC.
Still ' if u r having any queries regarding interview u can leave a comment down here!!
