The greater the what the less current there is for a given voltage?
Resistance is probably the missing word. I = e/R. If R is greater, I is less.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.
What are dangers of low voltage electricity?
please provide more detail, what do you mean low voltage? Also its not necessarily the voltage your worried about but the amount of current that can be supplied.
What are the reasons that low frequency parameters cannot be Measured in microwaves?
(a) voltage and current readings vary with position along the transmission line, (b) voltage and current are difficult to define in non-TEM transmission lines.
What happen when voltage decreases and current increases?
Yes. As long as the load stays the same. Voltage equals the resistance of the load times the current or amperage. Or , in this case, as an example, if the load is the same, the voltage is 240 and current is 10 amps. At 120 volts, the current is 20 amps. Current x resistance(or the load)=voltage. With simple math, the equation can be moved around.
What is the Primary function of a voltage follower circuit?
Its purpose is to provide approximately the same voltage to a load as what is input to the amplifier, but at a much greater current. In other words, it has no voltage gain, but it does have current gain.
Why are the readings on a ammeter always different?
The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
Is it true that for the same resistance the greater the voltage the greater the current?
true
Why do two ideal voltage source of unequal voltage cannot be connected in parallel?
If two ideal sources of unequal voltage are connected in parallel the higher voltage will provide a majority of the current (a two percent difference in voltage would provide an additional 5% of the current) and (in the case of batteries) the larger would provide charging current, quickly draining it.
Is emf current greater than current?
EMF is electromotive force. It is another name for voltage. Voltage is electric potential in joules per coulomb. Current is electric flow, in amperes. Amperes are coulombs per second. Voltage and current are not the same thing, and "emf current", or "voltage current" does not make sense.
What happen to the current when the voltage is greater than or equal to 6 volts?
The current is greater than or equal to (6) divided by (the effective resistance of the circuit).
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
The greater the what the less current there is for a given voltage?
Resistance is probably the missing word. I = e/R. If R is greater, I is less.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.
What will happen if current is more than required in diode?
If the applied voltage is greater than maximum forward voltage, the diode will get damaged..
