Table of several specifications (such as the transistor's current gain, beta) thatġ. Of the transistor - click on the "Show specs" button on the left this display a You can also inspect and modify the specifications Just click on the number with the mouse pointer andĮdite like any text field. You can change the input (base) resistor, the relay coil resistance, and the power
To see the current flow throught the transistor, click on the "Show current flow" button. The diode reduces the large transient voltages that are produced when the current through an inductor (the relay coil) is changed quickly by switching (called "inductive kick"). the collector current) exceeds aĬertain value, the relay switches on. The voltage level of the input can be changed by sliding the black arrow- head up andĬhanging the input voltage causes changes in the base current, collector current, A transistor switch is used to allow a 12 volt relay to be operated (turned on and off)
