The accuracy of the ammeter in the Yufong multimeter when set to 20A AC typically falls within a specified range, often around ±1% of the reading plus a certain number of least significant digits. To obtain the exact accuracy, it's best to refer to the user manual or technical specifications of the specific model, as these details can vary. Generally, multimeters designed for higher current measurements tend to have slightly lower accuracy compared to their lower range counterparts.
What else can I help you with?
The rms value of the resultant current in a wire which carries a DC of 20A and a sinusoidal ac of peak value 20A is?
From your description, this sounds like it is a sine wave offset to 10A, so the peak is at 20A, and the min is at 0? For this case, you have 10A DC (RMS) wave and a 10A Peak - neutral AC wave; The RMS value of the AC wave is: 10/2*sqrt(2) = 3.54A. So the RMS amplitude of this wave is 13.54A.
What is the wattage in the circuit?
wattage is voltage and amperage multiplied. example V/A=W or 120v x 20a=2400 watts
What is the amount of power loss on a transmission line that is transmitting 10 MW at 500 kV with 1000 ohms?
Line current = 10MW / 500kV = 20A Assuming the 1000 ohms is the resistance of the entire transmission line, end to end. Power loss = line current ^ 2 * line resistance = 20A ^ 2 * 1000 ohms = 400 KW
Would a 30A 240V circuit breaker be too large to safely support a either a 20A or 23A 240V bandsaw?
Yes it will operate it fine.

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.
Extension of a range of ammeter using a current transformer?
typically the ratio is on the current transformer it will say something like 100:5 witch means 5a meter becomes 100A full scale the 5 instead of a 1 gives you a hint about the capacity of the transformer its 20:1 so you could use it to make a 1A meter into a 20A but making a 10A meter into a 200A may lead to problems (accuracy or power)
What is 20a divided by 10?
2
What is 20a 45 factored?
20a + 45 = 5(4a + 9)
What is -4(5a-3)?
-4(5a-3) = -20a + 12
How many watts is 20A at 110v?
To calculate the watts from amperes and volts, you can use the formula: Watts = Amperes × Volts. For 20A at 110V, the calculation would be 20A × 110V = 2200 watts. Therefore, 20A at 110V is equal to 2200 watts.
What is 5a³ plus 15a² plus 20a?
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
How do you solve this equation -8 equals -20a?
12
What is the maximum current rating for a 20A wire gauge?
The maximum current rating for a 20A wire gauge is 20 amperes.
What actors and actresses appeared in 20a Stories from a Bus - 2007?
The cast of 20a Stories from a Bus - 2007 includes: Kris Cuppens as Driver
Can you use a 220V 20A fuse to replace a 125V 20A?
No, it is not safe to replace a 125V 20A fuse with a 220V 20A fuse. Fuses are designed to protect electrical circuits from overloading, and using a higher voltage fuse could lead to damage or fire hazards in the circuit. Always replace a fuse with the same voltage and amperage rating as the original.
Does the NEC code allow multiple 20A receptacles on a 20A circuit Put another way does a 20A receptacle with T shaped neutral slots imply that no other outlets are that circuit?
The National Electrical Code (US) allows up to thirteen 20 amp receptacles on a 20 amp circuit. 120V x 20A = 2400 VA each duplex receptacle is calculated at 180 VA 2400 / 180 = 13.3333 receptacles, since you can't put a third of a receptacle in, you have to round down to 13.
