To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.

How would you extend the range of a voltmeter and ammeter?

if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.


How increase the range of ammeter and volt meter?

Through the use of a 'multiplier', i.e. a carefully-calibrated resistor connected in series with (in the case of an analogue instrument) the instrument's operating coil.


How do you increase current capacity of an ammeter?

In measuring high AC currents a current transformer with a suitable rating say 100/5 or 1000/5 are used. The secondary current is usually 5 amps when the fulload current of 100 or 1000 as the case may be is flowing in the mains. It is the univerasl practice to use CT's for measurement of AC currents. In DC circuits the transformer method will not work, so to increase the current that you can measure you can allow a known amount of current to bypass the ammeter and recalibrate the ammeter. In other words, put a shunt in parallel with the ammeter.


How is the voltage measureing range of the basic analog meter movement extended?

shunt resistances are used to increase the range of ammetes and moreover it is praticularly then we have to low value shunt resistance.


What kind of ac ammeter does most electricians use?

I use a Fluke ammeter.


What is ammeter sensitivity?

Ammeter sensitivity can be determined by a change of scale for the ammeter which would introduce higher or lower resistance values depending on the reading required. A higher sensitivity for lower values of ampacity would require higher resistance in the measuring circuitry. Use Ohm's law to verify.


What do you measure with electric current?

I presume you mean what do you measure electric current with. You would use an ammeter.


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.

Which has higher resistance an ammeter or micro ammeter?

Micro ammeter has higher resistance. use ohm's law.. Say the voltage applied is 1 V. then for the ammeter.. I=1A, V=1V R=1 ohm for the micro ammeter.. I=0.000001, V=1V R=1000000 ohms
