Current Limiter Light Bulb. R1 35 0 7 30 2 5 410 ohms wattage for the above resistor would be p v2 r 35 x 35 410 2 98 or 3 watts. You can now turn your device on and watch the light bulb to see how bright it gets.
Now with your device off turn on the current limiter supplying power to your device. Make sure the switch on the current limiter is off and then plug your electronic device into the current limiter. Suffice here to say is that current in a series circuit is same at all point but voltage is dropped across each components.
Now with your device off turn on the current limiter supplying power to your device.
As the word implies the main purpose of this gadget is to limit current to a circuit. With that ladies and gentlemen let me come to the main topic of the day what is series bulb current limiter. The extension sockets they talk about for the current limiter need to be just the bare socket and then you attach a mains cord and hook the connections up with hook up wire. He told me it makes a good cheap current limiter when powering up new or vintage amps.
