What I have understood till now is that when step down transformer converts high voltage to low volt the diode converts a.c. To dc ...when we touch the bottom most wire of the sensor and along with it touch some other wire of at least one of the leds the circuit gets completed n d led glows....but I don't come to know then what is the use of cap there .....n why don't we get an electric shock when we touch the sensor wireWelcome to AAC.
I don't see how the LEDs can turn on for any significant time unless the cap is a supercap. The cap will charge up when the first LED is switched on. Thereafter there will be no LED current.
Yes, it's not going to work.I don't see how the LEDs can turn on for any significant time unless the cap is a supercap. The cap will charge up when the first LED is switched on. Thereafter there will be no LED current.
Because the transformer has reduced the available voltage to below that which will produce a shock.n why don't we get an electric shock when we touch the sensor wire
It would be mostly because the voltage is low, as noted. Think about a 12V car battery. You can grab both electrodes and feel nothing. Another reason is that, to get shocked, there needs to be a complete circuit including your body. Touching just one side of a DC voltage, even a fairly high one (say, 100V), won't shock you if you're not connected to the opposite pole. With very high voltage (say, >1000V), enough current can flow through unexpected paths such as your shoes, or the air, to complete a circuit.... why don't we get an electric shock when we touch the sensor wire
Yes, it's not going to work.
Maybe the capacitor was supposed to be connected as reservoir?
Or without the cap, but with its leads shorted.
I have a project made on this circuit n it works when we touch any of the sensor wires along with the bottom most wire.So the person's body is also included in the circuit n the respective leds glow
Creative thinker - yes.This circuit was made by an expert
