# Transistor

# Joulethief

A small current flows from the battery through the coil and the base-emitter path of the transistor. This opens the emittor-collector path of the transistor.

# Joulethief

Electricity is now able to travel through the second coil and through the collector-emitter channel of the transistor.

# Joulethief

The increasing amount of electricity through the second coil generates a negative voltage in the first coil. An negative voltage is induced in the first coil, which cause the transistor to close.

# Joulethief

With the transistor closed the energy starts to flow through the output (led).

# Joulethief

The inductor is now powered by the magnetic field of the coil.

# Joulethief

When the magnetic field is gone, the whole process starts over.

# Led

Make sure to get the LED polarity right. Short leg goes to ground!
