What will happen if emitter base is reversed bias and collector base is forward bias?

If emitter-base is reverse biased then there will be no amplification effect on collector-emitter. If collector-base is forward biased, it will act like a diode, but without emitter-base current, that is meaningless.


What Will happen to the watt meter reading if any two terminals get interchange d?

If any two terminals of a wattmeter are interchanged, the reading will typically show the same magnitude but with the opposite sign. This is because the wattmeter measures power based on the product of voltage and current, and interchanging the terminals reverses the phase relationship. Therefore, instead of indicating positive power flow, it will indicate negative power flow, which signifies power being fed back into the source.


What will happen if instead of npn transister pnp is used?

It really depends on the configuration of the circuit. A transistor can be connected in any of at least 3 configurations: common base, common emitter, and common collector. Each of these type of configurations determines where the source of electron flow is connected. After that, the biasing configuration needs to be determined, and this will change depending on whether you are using an NPN or PNP transistor. In the simpler biasing configurations, swapping a NPN for a PNP or vice versa will prevent current from flowing as the collector, base, and/or emitter will be reverse or forward-biased incorrectly. You would then either be blocking currently flow, or possibly causing a short circuit. Again, it depends on the configuration. Generally speaking, it is not a good idea. One potential result is you can damage the transistor or even destroy it or possibly damage other components in the circuit.


What will happen if the terminals of a batterr are accidentally left connected?

The battery might drain


What will happen to voltage divider circuit if emitter resistance is greater than collector resistance?

The gain of a class A, common emitter BJT amplifier, a fairly standard configuration, is defined as collector resistance divided by emitter resistance, or as hFe, whichever is less. Assuming that we are operating in a linear mode, and hFe is not a limiting factor, then the emitter resistance being greater than the collector resistance simply means that the gain is less than one.

What would happen if the emitter resistor fails to open?

This is an overcurrent condition, correct? The real answer is, "well, it's not SUPPOSED to open!" Which is true--if the emitter resistor opens, the smoke (which, as we all know, is the thing that makes electrical devices work) gets out and the circuit stops working. If you're in an overcurrent condition sufficient to destroy parts and you don't lose the resistor, the transistor being serviced by the emitter resistor is destroyed. Having said that, the circuit should be designed so the bias current is low enough that it won't destroy parts.

What will happen to the emitter current if the emitter base is reversed biased?

as we know that in reverse bias condition no current is produced and if it produced by the minority charge carrier then also the current produced is in very less amount so u can say that emitter current will reduced to large extend as compare to emitter current in forward bias condition

What will happen if terminals of the battery are reversed?

If terminals of the battery are reversed, it will short the device that is using the battery. On a car reversing the cables can blow fuses, melt wires, and fry computers.
