What will be the sensitivity of a 2000 Ma meter movement when it is used as DC voltmeter?
This full scale value will produce a voltmeter with a sensitivity of 20,000 Ω per V. The sensitivity is based on the fact that the full scale current of 50 μA results whenever 20,000 Ω of resistance is present in the meter circuit for each voltage applied.
How do you measure sensitivity with a multimeter?
The full-scale deflection current may also be expressed in terms of “ohms per volt” (Ω/V). The ohms per volt figure is often called the “sensitivity” of the instrument. Thus a meter with a 50 μA movement will have a “sensitivity” of 20,000 Ω/V.
What is voltage sensitivity of a voltmeter?
The sensitivity of a voltmeter is defined as the reciprocal or inverse of the full-scale deflection current (Ifsd) of the basic movement. It is denoted by the symbol S and expressed in Ω/V. Voltmeter sensitivity is also known as ohms-per-volt rating of the voltmeter.
What will be the sensitivity of a voltmeter with 0 to 7 Ma meter movement?
Explanation: Sensitivity of a voltmeter is the reciprocal of maximum current deflection. here sensitivity is reciprocal of 7mA.
What will be the sensitivity of a voltmeter for 0 to 50 ma meter movement?
What will be the sensitivity of a voltmeter for 0 to 50mA meter movement? Explanation: Sensitivity of a voltmeter is the reciprocal of full scale deflection of current. Here current deflection is given by 0 to 50mA and sensitivity is 20ohm/V.
What is meant by sensitivity of ohmmeter?
That is, the multiplier resistance and the coil resistance. Voltmeter Sensitivity. Voltmeter sensitivity is defined in terms of resistance per volt (Ω/V). The meter used in the previous example has a sensitivity of 20k Ω and a full scale deflection of 1 volt.
What is meter sensitivity?
The amount of current necessary to cause the meter pointer to deflect full scale is the meter sensitivity; it is an important characteristic of any meter. The sensitivity of a meter movement is the maximum current that the movement can measure. Any current greater than this value will very likely damage the meter.
What is voltage sensitivity?
Voltage sensitivity is the measure of the responsiveness of an appliance to the transform of applied voltage across it. A galvanometer is a type of ammeter. It is an appliance for detecting and measuring electric current.
What is volt ohm meter?
A multimeter or a multitester, also known as a volt/ohm meter or VOM, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance.
