What is the scientific notation of 0.0000000157?
1.57*10^-8, that reads as one point five seven times ten to the negative eigth.
On the 10a range the meter shows 2.56 does this mean two fifty six thousandth's amps?
No. The "10A" range means "please don't pass more than 10A through the meter while it's switched to this range".The display reads the current directly, i.e. 2.56 Amps.
What is the name of a number which reads the same when inverted?
The number that reads same when inerted is SIX.When inverted it reads SIX.
What is the name of the word which reads the same backwards and forwards?
A palindrome reads the same both directions.
What is a palindrome in maths?
A number that reads the same backwards as it does forwards. For example 1357531, or 121.
What is low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
Why is the electric watt meter connected in series with the rest of the circuits in the house?
First of all, you are referring to an energy meter, not a wattmeter. A wattmeter measures power, in watts, whereas an energy meter reads energy, in watt hours (or, more specifically, kilowatt hours). The energy company bills you for energy, not power.Having said that, the connections each instrument are the same. In fact, there are two coils inside an energy meter: a current coil, and a voltage (or potential) coil. The current coil is connected in series with the load while the voltage coil is connected in parallel with the supply voltage.The current coil measures the in-phase component of the current drawn by your load, so that the instrument always reads the true power (multiplied by time -the function of the aluminium disc) of the load -i.e. not the apparent power or reactive power.
What is a meter socket?
The electrical power that you use from the utility company has to be metered. This is done with a plug in watt meter. The meter socket is what holds the electrical watt meter. It is this meter that the meter reader reads to give you your monthly billing for the electricity that you used.
What instrument measures the amplitude of sound on a mobile?
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
If one test reads positive and the other one reads negative?
it's common to get a false negative, even if you are pregnant. but typically, if it reads as positive, you are pregnant
What is the meter reads number of miles driven called?
The odometer.
Does electric utility meter read real power or apparent power?
Electric utility meters typically measure the real power consumed by a household or building in kilowatt-hours (kWh), not apparent power. Real power represents the actual energy consumed to perform work, while apparent power represents the total power in an electrical circuit, including reactive power. Utility companies bill customers based on the real power consumed.
What does a con ed meter reader do?
Reads meters for Con Edison
How can the terminals of the diode be identified using the ohmmeter?
More commonly, the RED probe is on the banded (cathode) end of a diode, when the meter reads. You can also use a high ohms range (try around 200K) with a digital ohmmeter, not all have a specific "diode" setting. So test the meter first with a known marked diode, one that has a band on 1 end. You should get a reading with the probes around 1 way, and not the other. The probe on the banded end when the meter reads is the negative lead. Usually, that's the red one. So testing future diodes, if the meter reads, the red is the cathode of the diode. The polarity of the voltage appearing between the probes of digital and most analogue meters is opposite. The red lead of a digital meter is positive on the ohms ranges, while on most analogue meters the red lead is negative on the ohms ranges.
How to decide which is positive 6 volt dc equipment polarity test?
Apply your meter leads following standard red is positive and black is negative set your meter on dc volts touch leads to ends of battery if meter reads 6 v , the pole with the red lead is positive. If the meter spikes below zero than the black lead is on the positive pole.
How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
If a speaker reads at 112 dB1 watt1 meter how much power would need to be applied to give an output of 112 dB at 1 meter?
I think this question answers itself. If a speaker produces 112 db at 1 watt and measured at 1 meter distance, then obviously 1 watt is needed to produce 112db at 1 meter.
