What is advantages-of-parallel operation of transformer?
It enables an existing transformer to be upgraded to meet an increase in load, without having to remove that transformer and replace it with a 'larger' (expressed in volt amperes) one. It provides an useful way of using up a stock of smaller transformers.
How do current clamp on amp meters work?
clamp is an electrical device having two jaws which open to allow clamping around an electrical conductor. This allows properties of the electric current in the conductor to be measured, without having to make physical contact with it, or to disconnect it for insertion through the probe.
What is the current in 1KVA Transformer?
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.
How to stop Static current when my body touches metal part?
I m too having the same problem but unable to get rid off...
What will happen if a voltmeter has a low shunt resistance instead of having high shunt resistance?
The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.
Calculate the current taken by a 100 watts lamp having a working resistance of 200?
0.02 amperes
What is the voltage source of a circuit having a resistance of 16 ohms and drawing a current of 4.3 amperes?
According to ohms law... V=I * R So from the given values V = 4.3*16 = 68.8 Volts
What is meant by energy meter having ct ratio 5?
A CT, or current transformer, has a specified current ratio. The 5 in your question is the current supplied to the metering instrument at full scale. CT's current ratio is always full scale to 5, for instance - 200:5, 3000:5, etc.So, if a CT has a ratio of, say, 1000:5, this means when the conductor being measured is supplying 1000 amperes to the load, the CT will output 5 amperes to the instrumentation. The relationship is linear, so if the current is 500 amperes, the output will be 2.5 amperes, at 200 amperes the output will be 1 ampere, etc.This is done so the instrument can be designed always the same, with a 5 ampere input, no matter what size current is to be measured. Otherwise you would have to order (and manufacture) many different models of meter, one for each current range.The metering must be set, or programmed, with the CT multiplier, so it knows how much current is really flowing when it sees 5 amperes on the input.Similarly, we use PT's or potential transformers to reduce higher system voltages to a range that the instrument can also handle.
If the voltage is 12 volts and the resistance is 3 ohms what are the amps in this circuit?
Oh, dude, it's like basic math here. So, you just divide the voltage by the resistance to get the current. In this case, 12 volts divided by 3 ohms equals 4 amps. So, the current in this circuit would be 4 amps. Easy peasy lemon squeezy!
You want to take 25ams output you are having 16 Nos of 12V 8Ah batteries do you have to connect batteries in series of parallel connection?
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
How do we measure electrical current and electrical charge?
The definition of Electric Current in my books when I was learning is - the time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time. The definition of Electric Charge is - one of the basic properties of particles of matter enabling all electric and magnetic forces interactions, there are 2 kinds of charge Positive and Negative.Electric charge is measured by coulombs (coulomb is 1 ampere per second) and electric current is measured by amperes. If trying to measure use a ammeter.
What is an eletric current?
The time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes. See more.
What is charged by having a one way current flow through it?
A battery is charged by having a DC current flow through it.
Is effective an adverb?
No, it is an adjective. the adverb form is "effectively." (it can mean "in an effective manner" or "having the result of")
What are the current requirements to be a motorist?
The current requirements to be a motorist are having a valid driver's license, not having a suspended license, having car insurance and able to pass a vision test.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
Why does a car battery bubble when charging?
"Bubbling" of Electrolyte in Vehicle Batteries While ChargingThat is usually caused by having the charging rate[Amperes (Amps)] set too high.
