Current controlled.

Positive gate current turns on the device.

Turn off proces is uncontrolled and occurs when the forward current is lower than the holding current.

Voltage controlled.

When you apply voltage across the bridge, the path becomes conductive and carries current.

While Transmitting the high voltages from Grid stations the voltage is kept very high and current is kept Low. Doesn't it negates the Ohm's Law V=IR
Top Answer: The use of Ohm's Law here is in error. Lets not forget that this voltage is not being applied at the load ... Voir Plus
