Option 3 : 1, 2 and 4

Thyristor turn-on methods:

With anode positive with respect to cathode, a thyristor can be turned on by any one of the following techniques:

Forward voltage triggering: by applying sufficiently large anode voltage
Gate triggering: by applying sufficiently large gate current
dv/dt triggering: by applying anode voltage at a sufficiently fast rate
Temperature triggering: by increasing the temperature of SCR but at large values of temperature, the SCR may get damaged.
Light triggering

The following sentences form a paragraph.They are numbered as P, Q, R and S. These four parts are not given in their proper order. Read the sentences and choose the alternative that arranges them in correct order. P. It uses radio frequency identification (RFID) technology to make cashless payments through a prepaid account linked to it. Q. The tag, which is valid for five years, comes in seven different colours — violet, orange, yellow, green, pink, blue, black. Each colour is assigned to a particular category of vehicles. R. A FASTag is a reloadable tag that automatically deducts toll charges and allows a vehicle to pass through a toll gate without stopping for the payment. S. The tag is fixed to the windscreen of a vehicle and an RFID antenna in the canopy of the toll gate scans the QR code and the tag identification number, following which the boom barrier lifts to allow a vehicle to pass through.?

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since. S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
