What is value of R56K resistor?
56000 ohm or 56 Kilo ohm
What happens when you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms?
When you connect 230V ac supply directly to a diode with the help of resistor of the order kilo ohms, the diode will conduct on alternate half cycles. Forward bias current will be 230ma for 1KOhm, or 23ma for 10KOhm. Power across the resitor will be 25W for 1KOhm, or 2.5W for 10KOhm. Bottom line - the resistor will get very hot - and if not rated correctly, will be destroyed.
What is the function of igniter in hpsv lamp?
basically it generate high frequency.As you know when frequency increases voltage also increase.it produce frequency in kilo hertz.ULTIMATE function to produce high voltage,ie kilo volts.
What is the maximum inductor voltage when the inductor current is decreasing?
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
What is the time constant of a .05 microfarad capacitor and a 200 kilo ohm resistor connected in series?
The time constant of a 0.05 microfarad capacitor and a 200 K ohm resistor in series is simply their product, 0.05 times 200,000, or 10,000 microseconds, or 10 milliseconds. (Farads times ohms = seconds)
How can loading effect affect voltage measurement in a circuit?
Suppose you have two 100 kilo Ohm resistors in series across a 12 volt supply.The expected and actual voltage at their junction is 6 volts. Now measure the voltage across one resistor with a Voltmeter. The instrument must take a little power to move the meter needle or be taken by the digital circuitry. If the input resistance of the voltmeter is 100 Kilo Ohms then it will make that resistor under test appear to be 50 Kilo Ohms. The voltage across the resistor drops to 4 Volts. This is the loading effect of the voltmeter.
What is a 1k resistor?
It is a passive electrical device with a resistive value of 1000 ohms, used for limiting current or dropping voltage.
What resistor can you use to replace a 47 kilo-ohm resitor?
You should use the same size resistor; a 47 kilo-ohm.CommentThe correct spelling is 'kilohm'.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is 1k resistor?
the k is the Metric value kilo, or ,1000 so this is a 1000 ohm resistor
What is value of R56K resistor?
56000 ohm or 56 Kilo ohm
What is the definition of power in terms of energy and time current and voltage?
the formulae ; power = voltage x current applies, hence with 12 volts across a device e.g. resistor , and with 2 amps flowing in this circuit; a power of 24 watts will be developed across the load. this is instantaneous, and irrespective of time. however with time taken into account; with 24 watts of power being developed across the load for example, for 10 hours then; the amount of power being used can be defined as; 24x 10 = 240 watt - hours or 0.24 kilo watt - hours.

How do you measure volts in kva rating?
KVA means kilo volt amps or kilo Watts. A watt = 1 volt X 1 Amp. Kilo is shorthand for 1000. A watt is a measure of power, which is voltage x amps. Therefore it is not possible to relate voltage to KVA without additional information. Formula wise the above is correct but if you really need the voltage, it can be measured with a volt meter or VOM by putting the test leads across the output terminals of the KVA device.
What is the current drawn when you have a single phased load of 200KW is supplied at 500v through an overhead line with a resistance of 0.1ohm per conductor?
If the voltage is 500 volts, and the power is 200 kilo-watts, then the current is 400 amperes. (Watts equals Volts time Amperes)The resistance of the conductor has nothing to do with this calculation, but that fact that the conductors are 0.1 ohms means that the voltage drop across each conductor is 40 volts. (Volts equals Amperes times Ohms) Since there are two conductors, the total voltage drop is 80 volts, and the voltage available to the load will be 420 volts.
What does a 1k2 resistor do?
Resistors are components in electronic circuits that limit curent. 1K2 is a 1.2 Kilo ohm resistor. To say "what does it do" is too general a question. Suffice it to say that they are ubiquitous items that have many uses in electronics generally limiting current with effects on voltage when used properly in pairs or with resistive loads. Ted
Kilo voltage equal to how many regular voltages?
1000
