A discrete electronic thing - ANS-silicon controlled rectifier
a sine wave beginning at 0 levels will reach tremendous and terrible peaks at what two
factors ? - ANS-ninety and 270 degrees
Are zener diodes connected reverse or ahead biased in a circuit? - ANS-reverse
are zener diodes designed to function in opposite or ahead bias mode? - ANS-reverse
At what factor is counter electromotive force best in an inductive circuit? - ANS-whilst the
charge of trade for contemporary is maximum
Emits light while properly biased - ANS-LED
how can 3 phase voltage be stepped down the usage of transformer ? - ANS-through the
usage of a three phase transformer or 3 unmarried section transformers
How is an air coil magnetized? - ANS-present day is improved it finally reaches saturation
How many degrees does AC in a only inductive circuit lag voltage with the aid of? - ANS-90
degrees
if a cuircuit has a capacitor of five micro farads and a source voltage of a hundred and
twenty volts DC thru a resistant of 200 ok , how lengthy will it take to completely charge? -
ANS-5 seconds
if modern-day thru the burden will increase, contemporary thru the zener decreases. This
describes what sort of regulator? - ANS-Shunt regulator
if frequency is improved in a capacitive cuircuit , what's going to appear? - ANS-capacitive
reactance will decrease
if capacitors in parallel have same reactance of 40 ohms what's the overall reactance ? -
ANS-20 ohms
in a a hundred volt 60 Hz circuit, what's the full reactance with a 4 henry inductor in the
circuit? - ANS-1507 ohms
in a dc cuircuit whilst capacitors are gift , when is modern-day most ? - ANS-the instant
whilst power is applied
in capacitors , what is the cause of the dielectric ? - ANS-prevent acring within the capacitor
