Which of the following indicates that a silicon NPN junction transistor is biased on?

A bipolar junction transistor (BJT) consists of semiconductor layers. The base-emitter junction acts essentially like a forward-biased diode when the transistor is turned on. For a silicon-based component, a forward-biased PN junction has a characteristic voltage drop. This standard voltage drop is typically around 0.6 to 0.7 volts. Therefore, measuring this specific voltage across the base and emitter terminals is a clear indicator that the silicon NPN transistor is properly biased and conducting. The distractors often confuse voltage with resistance or get the decimal point wrong, such as 6 to 7 volts instead of 0.6 to 0.7 volts. Remember that standard silicon diodes and transistor junctions operate at a fraction of a volt, not whole volts or ohms.
