Only if you want to destroy the LED in short order.I have got a LED with wire connected to both terminals. There is no label on it. How do I know whether this LED could be used in AC or DC power.? Can I try this LED connecting with 240 AC volt with resistor in series?
Thank you
Very good point.the indicator light on your cooker is most probably a mains neon which is totally different to an led

I recommend you get that notion out of your mind... quickly.Ok. For neon bulb and LED, why it is necessary to limit current? Because I have tried connect one LED ihave to 9 DC volt. i have even connect to 12 vol dc. it glows well without demaging it. I kept glowing about 30 minutes. So with this expereince, i have in my mind it not really necssay to use resiissior in series.
Please throw light on this
I took this as a question unrelated to any plan by the OP to actually alter his appliance by attaching an LED (or even a neon bulb) to the mains. He's trying to learn how things work. Note that his experiments have been with DC power supplies....Actually my rice cooker is OK. but to learn electronic I have open the cooker to see. How it is connected. What is diference between the neon bulb and LEDs? how do i recognise? I am very new to electronic...
