Draw and explain the UJT characteristics?
The Unijunction emitter current vs voltage characteristic curve figure(a) shows that as VE increases, current IE increases up IP at the peak point. Beyond the peak point, current increases as voltage decreases in the negative resistance region. The voltage reaches a minimum at the valley point. The resistance of RB1, the saturation resistance is lowest at the valley point.Ip and Iv, are datasheet parameters; For a 2n2647, IPpand IVvare 2µA and 4mA, respectively. Vp is the voltage drop across RB1 plus a 0.7V diode drop; see Figure (b). Vv is estimated to be approximately 10% of VBB.
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What is voltage transformation ratio?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
What is the voltage that supplies a motor starter called?
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
How do we adjust the voltage of a shunt generator?
The voltage is adjusted with a potentiometer that adjusts the field voltage through the voltage regulator.

Is forward voltage drop of schottky diode more than tunnel diode?
Yes, the forward voltage drop of a Schottky diode is usually more than the forward voltage drop of a tunnel diode. A Schottky diode voltage drop is between approximately 0.15 to 0.45 volt. The interesting thing that makes a tunnel diode different from other diodes is its "negative resistance region" with a "peak current" around 0.06 volt and a "valley current" around 0.30 volt.

What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What are voltage stabilizers?
Voltage Stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator. Actually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
Formula for converting US voltage to India voltage?
There is no formula to convert voltage. Voltage is universal.
Is valley an adjective?
Valley is a noun. But it is used as an 'adjunct' or adjective to describe things in or about a valley: valley floor, valley streams, valley residents.
