Design a circuit that powers a relay through a transistor and relay operates any kind of external device, like a DC motor.
Design a circuit that could operate a 60 watt (ac load) bulb through a relay. (rebuilt this circuit here

 

Funny: I read the title as "**** ant". Made me click...

 

You are indeed new to the AAC forum and has violated a big rule!!

You're being generous, Eric. I'm sure it's more than one.

Done...

Wait, did you want me to post it here!?

 

Do they not have Google in your country? Perhaps it is time to brush up your Google skills hint transistor+relay+driver

 

Or perhaps it is time for a truly revolutionary concept -- make an attempt to work YOUR homework and then post your efforts and ask specific questions about what is causing you difficulties.


I'm betting on another one-post wonder. Any takers?

That has always been the *number 1* rule here!
