Basic electronics components: diode, Led, Capacitor, Coil, …

The coil is an inductor and is measured in the unit Henry (H). A simple coil consists of an iron core wrapped with the copper wire. If a DC voltage is applied to a coil, the current flows through the coil and only builds up a magnetic field there. To put it simply: the current flowing into the coil takes some time until it flows out of the coil ...

Does combining two separate transformers double the voltage?

A basic transformer secondary is isolated from the primary, but there could possibly be something like a ground connection between one side of the primary and one side of the secondary. This is unlikely since the 6 kV would be much safer if it were completely isolated from the power line and ground, but it could be worth checking the ...

Initial Testing of a DRSSTC Tesla Coil

With a gate transformer in place, the secondary winding of the gate transformer that connects to the IGBT acts as a DC short and thus will short out the gate input to the emitter ensuring the IGBT stays off during this test. Connect a multimeter set to DC volts across your DC bus capacitor stack.

Electrical Transformer Explained

Why do transformer use the units of KVA instead of Kilowatts? The transformer is just transferring power between coils, so we use the volt amp units. The kilowatts depend on what you connect to the transformer. The manufacturer doesn''t know what you will connect to the transformer so they state the total rated apparent power in volt-amps.
