dear everyone!
i polarize tip122 with power supply 33.6V DC with a resistor 5.1k. but it not working. i measure the voltage, one side of resistor 5.1k connect to power supply is 33.6v and the other of resistor conenct to pin Base of tip122 still OV! anyone have knowledge about this, teach me, plz!thank all.
