Electronics - Voltage and Current - Discussion

It depends on operating voltages.

Thanks sourav for the answer.

But can you tell me in the example you mentioned above, if another motor is also connected to the closed terminal of the relay (the previous motor also connected) , and we provide 6. 1volt, then which motor will turn on?

@Anusha:
U get it na, that SPDT hav one input and Two output lines. The best example of SPDT is Relay. I will giv u bettr example, assume that u have relay of 6v, it hav two output normally open and normally closed. Relay hav its main input connectd to that normally closed terminal. Assume u hav connected a motor to normally open terminal. And there is nothing connected to that normally closed terminal. When u giv voltage upto 5.8v to relay, ur motor will not run. But as u giv voltage to relay of 6.1v ur motor which is connected to normally open terminal, will start to run. This is how relay works with the best example of SPDT swicth.

May I know what is the use of these switches separately ? I mean to ask practical use of each switch so that it becomes easy to understand.

spdt- single pole double through switch
spst- single pole single through switch
dpst- double pole single through switch
dpdt- double pole double through switch

Give full form of spst, spdt, dpst, dpdt and it's application.

Please.

Thanks.

Just a calling bell or horn etc are the example of push button, where by until we press the circuit will be closed past and operate and while realizing it come back to normal position.

What is push button? please give an example.

What are the symbols for the rest?
