How is an ammeter connected to reduce frequency errors?
Connecting an ammeter does not reduce the frequency errors.
How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
What happens on Ammeter when load is increased?
It depends on the configuration of the ammeter. If you have an ammeter with red on one side, green on the other, and a balance point in the center, the needle will go into the red when when load is increased in relation to the charge. If the load is decreased in relation to the charge, the needle will go into the green. If you have an ammeter with a numerical value (i.e. 30, 40, 50, etc.) then the needle will go up to the value of the load present in the system not in relation to the charge.
What is the maximum current that you can measure by multimeter?
A ammeter (not 'current meter') will read currents up to the maximum value indicated on its scale (analogue instruments) or its range setting switch (digital instruments).
What is more efficient heat pumps with or without gas back-up?
with gas back up . a heat pump alone ,will not be able to extract heat efficiently when it reaches it's economic balance point in its region of operation.
Does cigarette smoke travel up or down in a closed room?
In a closed room, cigarette smoke tends to rise upwards due to its heat and buoyancy.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.

Should you heat up electric curlers with the lid open or closed?
Well, honey, it's simple physics. You should heat up electric curlers with the lid closed, just like you wouldn't cook a casserole with the oven door wide open. Keeping the lid closed helps retain the heat and ensures your curls come out looking fabulous. So, close that lid and get ready to rock those curls!
Breeze no heat and overheating what causes this?
No heat coming from the heater and the car overheating is usually the thermostat stuck closed. The thermostat is supposed to open up at a certain temperature allowing the engine to warm up quickly.
How do you calculate the ammeter reading?
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
Why a school might ask teachers to keep the windows closed and the shades down during a heat wave?
It will be easier for the heat to spread into the school when the windows are open and shades are up because of radiation.
How can you use hit and heat in a sentence?
Sure, darling. Here's a sentence for you: "I hit the snooze button on my alarm clock this morning because I couldn't handle the heat of waking up early." Boom, hit and heat in one sentence. You're welcome.
What is the calibration of ammeter?
An ammeter should not be used as a voltmeter. An ammeter is a low impedance device that measures the current going through a circuit, often by measuring the small voltage across a known resistance. A voltmeter is a high impedance device that measures the voltage across a circuit. If you were to connect an ammeter as if it were a voltmeter, you would effectively short out the circuit, drastically affecting its operation, and potentially damaging both the circuit and the ammeter.
What happens on Ammeter when load is increased?

If you have an ammeter with red on one side, green on the other, and a balance point in the center, the needle will go into the red when when load is increased in relation to the charge.

How do get the total ampere when a using 12 volt?
Use an ammeter connected in series with the supply. Make sure the ammeter is of sufficient size to cope with the maximum current. Add up all the wattages of devices used (stamped on them) to get a clue as to how much it may take. Divide the wattage by 12v to get Amps. On a vehicle, do not crank the engine with the ammeter attached to the battery. Unless the ammeter can stand several hundred amps. (Unlikely)
