The only way to close an SCR is with:

The TRIAC is equivalent to ________________.

An optically coupled isolator is a device containing _________ in a single package.

A TRIAC:

The DIAC conducts in only one direction when gated on.

The gate of a TRIAC can turn it on to have current flow in either direction.

The optically coupled isolator interrupter module is used to transfer switching information between two electrically isolated points.

When checking a good SCR or TRIAC with an ohmmeter it will:

A DIAC is a bidirectional diode that has a symmetrical switching mode.

A transducer does not convert energy from one form to another.

SCRs are four-layer devices that are either fully conducting or not conducting.

A photodiode is a device that produces light.

To turn an SCR off, simply remove the gate voltage.

What does a hall effect sensor sense?

What causes the piezoelectric effect?

A semiconductor using the hall effect will detect magnetic fields.

A TRIAC will control AC voltage during the positive half cycle only.

A TRIAC can be triggered or activated by either a positive or a negative input gate trigger.

A thermistor is a semiconductor device that acts like a piezoresistive resistor.

The silicon-controlled rectifier (SCR) is a three-layer device consisting of a gate, an anode, and a cathode.
