How do you find out 3 phase motor watts?
It should me stamped on the information plate.
If this is not on it, then there will be the running current stamped on the plate. Multiply this by the supply voltage to find the power in watts. Take the horsepower of the motor and multiply it by 746. There are 746 watts in 1 HP. It is also the same for single phase motors.
How does an astable circuit work?
astable network means it has only one stable state.so the circuit need trigger input to change to another stage and it automatically changes to the previous stage when the process completed with the use of the capacitor.
Historically, transistor-transistor logic (TTL) voltage levels have been 5.0 volts, with a high being any voltage above about 3.5 volts and a low being any voltage below about 1.5 volts, with lots of variations on the high/low cutoffs from part to part. Since about 2001, however, most processors have been using low-voltage TTL (LVTTL), which has a nominal voltage of 3.3 volts (approx >2.2 volts for high and approx < 1.2 volts for low). Hence, many parts advertised as "TTL" today actually work at 3.3 volts rather than 5.0 volts.
How do you repair keyless entry circuit board for 99 Chrysler Sebring Convertible?
take it to your near autozone,they started making some aftermarket products,if they don't have one for your vehicle take it to a Chrysler dealership and they will match one up but if they have to reprogram it, it will cost extra along with the keyless entry,sometimes they don't have to reprogram them.
In what ways can a transistor amplifier modulator be modulated?
If I remember correctly, the definition of "modulation" is a "change in amplitude or frequency".
What is the definition of electronics engineering?
electronics engineering is the branch of engineering which deals with the flow of current in a semiconductor devices/components.
Semiconductor devices/components are those element which made from semiconductors like silicon germanium GaAs and other material.
they are widely using in current generation.
What is the difference between oscillating and rotational motion?
Rotational motion is motion which emulates that of the minute hand of a clock. Oscillating motion is motion which emulates that of the pendulum.
dynamo
How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R.
for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
State 5 type of temperature measuring devices other than thermocouple with its application?
RTD - Resistence temperature detector
Thermistor
Pyrometer
Thermometer
What is lookup table in microprocessor?
The lookup table in a microprocessor is a system that helps replace the runtime computations. It replaces them with an easier index operation.
What is the function of the resistor into capacitor?
A RC circuit is a simple filtering circuit. The impedance of R will stay the same across the frequency band. The impedance of C will vary according to 1/jwC (j = i = imaginary number, w = omega/frequency in radians, C = capacitance in Farads). As frequency varies from low frequency to high frequency, an increasingly smaller amount of the signal voltage will "drop" across the capacitor. This is known as a first order (one reactive element, the capacitor) low pass filter if the desired signal is measured across the capacitor. If measured across the resistor, this would be a first order high pass filter.
Edit: if you are talking about ESR (equivalent serires resistance), it is a parasitic component inside a capacitor. Theoretically, you don't want it but it's there.
Constructional difference between preset and potentiometer?
WE USE Preset in a circuit to work it perfectly by adjusting a value & we cant change the value of preset after its working.
Potentiometer can be used to vary from (0-n)
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance.
Ohm's law: Current equals voltage divided by resistance
A: It is an IC which contain an led which will couple the input to another device within the package it can be a transistor a triac scr and so forth. is main purpose in application is to isolate the source from the output.
Does series field winding have more resistance or a shunt field winding?
shunt field winding have more resistance than series field winding

Can operational amplifier be used to sum or more signals?
A: Sure by adding or subtracting from different inputs or scaling with different value of resistors
What does not provide a voltage a difference in a circuit?
Wires do not provide a voltage difference
AnswerAs 'voltage' is synonymous with 'potential difference', you appear to be asking "What does not provide a potential difference difference in a circuit?", which does not make any sense!
Is discrete is a type of resistor?
A discrete component is one where the package contains only one circuit element. The opposite is an "integrated circuit" (aka a "silicon chip" or "chip") where a package contains many circuit elements.
It's not that "discrete" is a type of resistor, it's that a resistor is a type of discrete component.
Why does impulse noise has more impact on digital signals than analog signals?
Go back to your teacher/lecturer/tutor and check the question..
My experience shows that it's the *opposite* way around.
