Assertion: transistor's voltage | /r/CapableOf | apply to base pin
Facets:
Source sentences:
text: If the transistor is NPN type, we need to apply a voltage of 0.7v to trigger it and as the voltage applied to base pin the transistor turns ON which is the forward biased condition and current start flowing through the collector to emitter (also called saturation region).
text: When the button is pressed, voltage is applied to the base pin and the LED is turned off.
