Hey Traveler! Next to me is a step down transformer, its like a magic tool that takes high voltage and turns it into lower voltage—kinda like making a big zap into a smaller zap!, It does this by using two coils of wire wrapped around a metal core. The electricity in the first coil creates a magnetic field that makes electricity in the second coil, but with less voltage! Now, if you connect an LED directly to it, the LED flickers because the electricity is still AC, which goes back and forth....
