Ammeter Range Formula at Daniel Kinsey blog

Ammeter Range Formula. Calculate the value of shunt resistance required to convert the pmmc meter into a dc ammeter with a range of 0 to 5 amperes. A meter designed to measure electrical current is popularly called an “ ammeter ” because the unit of measurement is “amps.”. The formula to increase the range of an ammeter is derived in the following way: In ammeter designs, external resistors added to extend the usable range. Let \(r_{sh}\) = shunt resistance \(r_m\) = internal resistance of coil. Shunts are used for dc and ac measurements while the current transformers are used for ac measuring instruments only. The ammeter would have the same reading if located between points. All of the current in this circuit flows through the meter. An ammeter (a) is placed in series to measure current. An ammeter, with a 100 ω meter. The below equation is a mathematical representation of the relationship between input voltage and current to the ammeter and the value of input resistance. The measurement range of an ammeter. It is possible to extend the range of an ammeter by using a shunt. I = maximum range required. From this, a moving coil ammeter range can be extended by using shunts,.
