What is used to measure a current in a circuit?
An ammeter either directly, or via a current transformer, is used to measure current in a circuit.Current transformers (CTs) are necessary when either (1) you need to measure the large currents flowing in high-voltagesystems (a CT will isolate the HV system from the ammeter to which it is connected, as well as reduce the value of the HV current) or (2) you need to reduce the very large currents to be measured in medium-voltage systems.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com
How do you reduce kwh by caacitor using?
To reduce kWh by capacitor is when a motor is put in. The terminal voltage is reducing and current is increasing it is connected parallel with the motor.
Are ammeters connected in series with the circuit under test?
Ammeters are connected in series with the circuit under test. Even the clamp on ammeter is a series device, taking advantage of the fact that the conductor is a half turn transformer winding that you can measure the current through.
Which device use for reduce distortion in sound?
This can be done with an Equalizer. ANSWER: Not an equalizer for sure not unless the distortion is frequency related.
What is a description of the loading effect of an ammeter?
loading of an ammeter in a circuit decreases the flow of current,so it has to be calculated to reduce expected errors in the operations

How do you reduce frequency in speakers?
Using a crossover, you can limit the frequency response of the signal sent to speakers.

What are 3 ways to reduce resistance?
divide frequency
Why are lightness important?
they reduce the frequency of crashes hope this helps:)
Which of the following is not a consideration regarding the fourth principle solution reduce the frequency?
slow down production to ensure frequency is reduced
Why should a millimeter have a low resistance?
An ammeter is placed in series with a circuit in order to measure the current. If it has any appreciable resistance, inserting the ammeter will increase the normal resistance of the circuit and reduce the value of the current flowing through it. The ammeter will, therefore, give an inaccurate reading (under-read). So the ammeter must have a very low resistance so that it has the minimum effect on the normal resistance of the circuit being tested. Ideally, the ammeter should have zero resistance but, of course, this is impossible.
Why traffic lights are important?
they reduce the frequency of crashes hope this helps:)
What is the lowpass filter cutoff frequency that must be used to decimate to reduce the sampling rate from 8kHz to 4kHz?
2kHz - That's the nyquist frequency at a sample frequency of 4kHz.
