Please choose the correct answer and explain if possible. Thank you. 4. The main terminal voltage across an ON conducting SCR depends on the instantaneous main terminal current in the following way: a. They are proportional b. The voltage increases as the current increases, but no quite proportionally c. The voltage increases as the current increases, by a squared (seond power) relationship d. They are virtually non-related 5. To turn Off a conducting SCR in a dc-powered circuit, it is necessary to: a. Interrupt (stop) the gate current b. Wait for the main terminal current to fall below IHO when the supply voltage crosses through zero c. Deliver a pulse of negative gate current via the gate lead d. Place a temporary reverse bias across the SCR’s main terminals 6. In a simple RC charging circuit used for trigger-control of an SCR, a good range of adjustment of the RC time-constant is: a. 1 to 5 msec b. 1 to 30 msec c. 0.1 to 10 msec d. 2 to 25 μsec
