What else can I help you with?
Direct current 12v to 10v to increase amps?
using a step-up transformer. ****warning***** will stress a power supply
What are some precautions do you take when using a milliammeter?
1. Use the meter in its rated range. 2. Connect it in series to measure the current.
What converts an alternating current to diredt current?
Alternating Current can be converted to Direct Current by using a DC Converter which contain a Bridge Circuit , a Capacitor and if needed a Transformer.CommentA 'DC converter' is normally called a rectifier.
Advantage of a transformer over a transformer coupled circuit?
Sounds more like a "homework" or "test" question, rather than a real-world question, and vague, at that! Could you re-phrase your question in a better, more-precise context, or check it for typos? Right now, your question seems to ask "What's the advantage of using a transformer, instead of using a transformer-coupled circuit?"...which makes no sense, since a "transformer-coupled circuit" USES a transformer.
Convert 230v to 5v with out using transformer?
Why are you asking someone to do your homework for you? Ask your teacher.
How do you step down current?
by using current transformer
Advantages of current transformer?
A CT allows:heavy currents to be measured using conventional ammeters, andelectrically-isolates the ammeters from high-voltage primary circuits.
What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
How do you test a current transformer using a digital signal processor?
You don't.
Why is a transformer used?
To step up or step down a particular voltage using the principle of electromagnetic induction. This is a potential transformer. Transformers are also used to step up or step down current. Current transformers are used extensively in instrumentation applications. Current and voltage are inversely proportional.
What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Can you amplify the AC in your data center using an AC transformer and how?
Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.
What are the advantages of instrument transformer?
'Instrument transformer' is the collective name for current transformers (CTs) and voltage (or 'potential') transformers (VTs/PTs). These transformers have two functions:to reduce the current or voltage in a high-voltage primary circuit to values that may be measured using regular ammeters or voltmeters ('burdens'), or to provide the current or voltage inputs to protection relays.to electrically-isolate their secondary burdens from the high-voltage primary circuit for the purpose of safety.
Why are stripes of iron plates joined instead of using a single block of iron core in a transformer?
To reduce heat generated and eddy current losses in transformer's core during operation.
Is a current relay same as potential relay?
current relay are using for over current low state & high state.but potential relay are related to voltage.
Direct current 12v to 10v to increase amps?
using a step-up transformer. ****warning***** will stress a power supply
More the transformer impedance less the fault current... so is a high value of transformer impedance good for it?
It depends a lot on the application, i would go with low impedance transformers if am using the transformers for distribution as it will really increase the the maximum fault current. If am using the transformers as step up specially for generators or to charge capacitors, using a high impedance transformer is a good idea as it will decrease the inrush current of the system. you have to see your application and decide what fit that best.
