peak inverse voltage :- it is the maximum voltage above which if applied the diode gets destroyed. Here destroyed in the sense the p-n junction gets destroyed due to breakdown voltage, it behaves like a straight conducting wire (which is of no use).

What is the current through the 150 ohm resistor?

It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).


What is Meaning of diode rating?

There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.


What is impedance voltage in a transformer?

Power transformers have an impedance (Z) rating that is listed in %. So the nameplate might state 5% Z for example. What this means is that when the secondary conductors are bolted together then 5% of the rated primary voltage is applied and will generate 100% current in flow in the secondary. Example: you have a 75KVA Delta-Wye 5% Z transformer with a 480V primary rating and 208/12 secondary rating. The amp rating of the secondary is 208A [75,000/(1.732x208)] So if you applied 24VAC to the primary with the secondary bolted together with busbar then you would have 208A of current flow.


What will happen if higher rating capacitor is used in fan?

It will rotate faster.Since the fan is not designed for this, it will progressively ruin it.


How does the Resistance and Wattage relate to maximum voltage of a wirewound resistor?

The power rating of a resistor is determined by its physical size. The greater its surface area, the better it can dissipate energy, so the higher its power rating. Knowing its power rating and its resistance will determine the maximum voltage that can be applied to it in order to ensure the resulting current doesn't cause the resistor to overheat. This can be determined by manipulating the equation, P = U2/R.

Cost per rating point?

The cost of reaching one percent of the target population. CPP is calculated by dividing the cost of the schedule by the gross rating points. National and regional advertising buyers frequently use this cost efficiency measure, since it can be applied across all media.The cost per rating point is used to estimate the cost for TV advertising on several shows.Cost per rating point = Commercial time costPercentage of audience.


Cause of burnout of two resistor?

Too much current flowing in circuit. Sounds like a voltage was applied that exceeded the rating of the resistor. Resistors are rated in watts which is Volts times Amps. As an example, you might have a 1/2 watt rated resistor. If you applied 120 VAC across a 10 Ohm resistance then the current would be 12 Amps. The wattage would be 1,440 watts which is well in access of the rating and would certainly burn out the resistor.
