After that, Power-up & tests the circuit. The simplest way to switch moderate to high amounts of power is to use the transistor with an open-collector output and the transistors Emitter terminal connected directly to ground. On the other hand, if the conductors are disconnected, the current will not flow, meaning no signal will be produced. Since fT is a transistor parameter listed on datasheets, this answers your question. To make it less of a hassle, we can insert a toggle switch in the circuit so that we can just toggle the lever of the toggle switch if we want to turn ON or OFF the light bulb, instead of connecting or disconnecting the electrical plug.
