To measure which of the following is an ammeter used?
Electric current
An ammeter is an electrical instrument used specifically to measure the magnitude of electric current flowing through a point in a circuit. Based on the function of the ammeter, it is designed to measure electric current .
Important Questions from Basic DC Ammeter
The range of an ammeter can be extended by using:
- Why we use low internal resistance in series of an ammeter?
A moving coil galvanometer is made into a DC ammeter by connecting
A (0-50)A moving coil ammeter has a voltage drop of 0.1V across its terminals at full scale deflection. The external shunt resistance (in milliohms) needed to extend its range to (0 - 500 A) is –
Two ammeters x and y have resistances of 1.2 Ω and 1.5 Ω respectively and they give full scale deflection with 150 mA and 250 mA respectively. The ranges have been extended by connecting shunts so as to give full scale deflection with 15 A. The ammeters along with shunts are connected in parallel and then placed in a circuit in which the total current flowing is 15 A. The current in amperes indicated in ammeter x is-
