you need a some iron and it is joined to led light and give us ground and plastic body. then it is make current tester
Making process of a tester which can detect current is as follows -
• Things required :
- A clean and thin iron wire of 1 mm diameter.
- Electrical tape.
- Nichrome wire.
• Making process :
- At first take the nichrome wire and remove the insulation on the wire(if any).
- Then make a small loop of the nihrome wire and firmly attach that loop in one end of the iron wire.
- Then wrap around the iron wire by the electrical tape and only leave the both ends of the wire.
- Then hold the setup by touching only the insulation area made by electrical tape.
- And touch the conducting wire by the open end of the iron wire.
- If there is any kind of electricity then the loop of the nichrome wire will become red hot in some time and will produce significant amount of light rays.
