Practically all analog meters are a coil movement of 50micro amps or so to measure a 50amps then becomes a problem the meter will destroy itself. However is a very small shunt of resistance if placed in the path of the 50 ampere flow then a small voltage drop will develop a Mv. THAT A METER CAN SAFELY READ. this voltage drop can be calibrated to show a 50 ampere full meter deflection. Therefore read Mv to get amps. It should be noted that since the small resistance is in series with the circuit there will be an error caused by the shunt resistance. Bottom line it should be small in value as possible to reduce this error for accuracy sake. Digital meter will function the same way as an analog meter meaning shunt mv reading for full scale readout.

Why does voltmeter have high internal resistance?
No, ammeters have a low internal resistance. This is so that when they are put in series with a circuit, they change the circuit's operating characteristics as little as possible.Contrast this with voltmeters, which do have a high internal resistance, and which are intended to be placed in parallel with the circuit they are measuring.Use the link below to the related question on why ammeters have a low internal resistance and read through that information to see why things are the way they are.
What will be the inductance in inductive circuit at low frequency?
The inductance doesn't change, but the impedance (equivalent to resistance) will be very low.
What is micro-ohm test?
A micro-ohm test is a measurement technique used to assess the electrical resistance of materials, particularly in low-resistance applications such as connections, busbars, and grounding systems. It typically employs a specialized instrument that applies a known current through the component and measures the voltage drop to calculate resistance in micro-ohms (millionths of an ohm). This test is crucial for ensuring the reliability and efficiency of electrical systems, as high resistance can lead to overheating and inefficiencies. It is commonly used in industrial, electrical, and maintenance applications.
Why should you be the internal resistance of the very few Amitr?
ammeter connect in series in circuit to measure the current, if the Ammeter have a high resistance it would effect the voltage value because there will be a drop voltage over the internal resistance of the Ammeter, so we desgin the ammeters with very low resistance...
How does analog switch AD7512 works?
It can connect 2 pins with a very high resistance and with a quite low resistance, depending on the voltage of the corresponding input pin.
What instrument measures very low temperatures?
hello
What are rossetti french horns like?
They play at very low quality and have high resistance to play loud (which means dynamics are terrible on it) . A cheap Chinese instrument
What electrical measuring instrument is used to measure polarity index test?
A low resistance ohmmeter is used
Is the bass drum a very low but big instrument?
yes, quite low and quite large
What is humidity What is the name of the instrument that measures it Which is more comfortable a day with high humidity or with low humidity?
Humidity is dampness in the air. The intrument that measures it is a hygrometer, and a day with low humidity is more comfortable because its easier to breath

Why armature resistance is less than 1 Ohm?
why armature resistance is very low as compare to field resistance in dc motor
What is the term for the materials that have very low thermal energy resistance?
superconductors
1.low resistance in n-p direction . 2. High resistance in n-p direction . 3. Very low resistance in n-p direction . 4. Double the resistance in n-p direction. Reason for rectifying action ofdiode?
The question doesn't describe1). What is low resistance ?2). What is high resistance ?3). What is very low resistance ?4). Double the resistance compared to what ?The reason for the rectifying action of a diode is the difference between itsresistance in one direction compared to its resistance in the other direction.In other words, its non-linearity.
What is the term fornmaterials that have very low thermal energy and resistance?
The term for materials that have very low thermal energy and resistance is insulators. Insulators prevent the transfer of heat and electricity due to their high electrical resistance and low thermal conductivity. Examples of insulators include rubber, glass, and plastic.
What pitch would the sound from a large instrument have?
the bigger an instrument is, the lower the sound that it makes
How do you identify the polarity of a diode when the tester is on resistance scale?
ln reverse biase high resistance and in forward biase very low resistance
