Trye or false The overload contact must be connected in such a manner that it will cause the output of the circuit to turn off if it opens.

Most analog sensors can produce only very weak signals.

Insulators are generally made from lightweight materials that have small atoms.

The diode is often called a PN junction.

The unijunction transistor $($UJT$)$is a special transistor that has two bases and two emitters.

The pulse rate is determined by the amount of resistance and capacitance connected to the emitter of the UJT.

The silicon$-$controlled rectifier $($SCR$)$is often referred to as a PNPP junction.

To phase shift an SCR$,$the gate circuit must be unlocked, or separated, from the anode circuit.

Voltage applied to the diac must reach a predetermined level before the diac will activate.

When a triac is connected in an AC circuit, the output voltage is alternating current.

Pin $2$of a $555$timer must be connected to a voltage that is less than $110$Vcc$($the applied voltage$)$to trigger the unit.
