7. The cathode of a Zener diode in a voltage regulator is normally: (a) more positive than the anode (b) more negative than the anode (c) at +0.7 V (d) grounded. 8. For a certain 12 V Zener diode, a 10 mA change in Zener current produces a 0.1 V change in Zener voltage. The Zener impedance for this current range is: (a) 1 ̐ (b) 100 ̐ (c) 10 ̐ (d) 0.1 ̐. 9. The mobility of electron in material is expressed in unit of: (a) V/s (b) m2/V.s (c) m2/V (d) J/K. 10. The revered biased PN junction, the current through the junction increases abruptly at: (a) breakdown voltage (b) 0V (c) 0.2 eV (d) 7.2 eV. 11. In an intrinsic semiconductor, the number of free electrons (a) Equals the number of holes (b) Is greater than the number of holes (c) Is less than the number of holes (d) None of the above. 12. The battery connections required to forward bias a pn junction are (a) +ve terminal to p and -ve terminal to n (b) -ve terminal to p and +ve terminal to n (c) -ve terminal to p and -ve terminal to n (d) None of the above.

The anode of an electrolytic cell must be connected to which terminal-positive or negative-of the power source?

Transcript

00:01 The anode for a genad diode in voltage regulator is normally.

00:05 The positive end of diode is called anode and so the positive end is called anode and negative end is called cathode and so the flow of current from anode end to the cathode but not the other direction.

00:24 Therefore for anode in a genad diode in voltage regulator is normally...
