Which thyristor conducts current in both directions when turned on?

SCS

DIAC

SUS

SCR

A proximity sensor that operates under the principle of Faradays Law of Inductance

Inductive sensor

Optical sensor

Capacitive sensor

Magnetic sensor

Why do most op-amps use a commoncollector at the output stage?

To have a better frequency response

To have a very low output resistance

To have a low harmonic distortion

To have a higher output power

Why do FETs offer high input resistance than BJTs?

Due to the level of doping

Because of the materials used

Because of the way FETS are constructed.

Due to the reverse-biased input circuit of FETs.

Normally, diodes will not conduct when reverse-biased, but if the reverse voltage is increased further, a point will be reached where the diode gives up and allowing the current to surge. This voltage is one of the limiting parameter of diodes is known as

peak reverse voltage (PRV)

Peak inverse voltage (PIV)

breakdown voltage (Vbr)

All are correct
