Is there any possibility to connect motor with high voltage or led tv with relay to on/off them with raspberryPi???
I'm trying to on/off electronic devices with RPi. I found that relay is used to connect light.But i have no knowledge how to control high voltage devices....

I've no idea what's difference between 3.3v , 5v , 9v,12v relays.
Please help me.

W.r.t. "I've no idea what's difference between 3.3v , 5v , 9v,12v relays" - that's, usually, the voltage needed to "power" the relay (coil) itself. W.r.t. "high-voltage" switching you need to check the voltage/current rating of the relays switch contacts..

You might want to edit out your email address to avoid spam.

And with respect, if you don't understand different relay coil voltages, you are not ready to start wiring up mains relays. Mains voltages are dangerous, your life is at risk (not to mention the possibility of starting a fire). If you do go the DIY route, please get someone with more understanding to check your wiring BEFORE switching on.

There are ready made modules for (remotely) switching mains controlled by a Pi. I haven't used them and can't make a recommendation, but look at the products from the official Pi suppliers.

Hi, here is my post about relay (5V):
