How do you calculate multiplier resistance?
The resistance of the multiplier can be computed by the following formula: multiply the ohms per volt by the full-scale deflection; then the product by the desired multiplier ratio; and subtract the resistance of the moving-element.
What is multiplier in multimeter?
Multiplying Factor is basically the value by which the range of voltmeter can be extended. Let’s assume that the moving coil of voltmeter can sustain a voltage of 0.25 V and if we want to use it for measuring a voltage of 10 V then Multiplying Factor = 10/0.25 = 40.
What is multiplier in measuring instruments?
This series resistance is called a multiplier. The main function of the multiplier is to limit the current through the basic meter so that the meter current does not exceed the full scale deflection value. The voltmeter measures the voltage across the two points of a circuit or a voltage across a circuit component.
What is the value of multiplier resistance?
Therefore, the value of the multiplier resistance for the 0- 100-V range is equal to R1 plus R2. Similarly, the multiplier resistance for the 0-1000-V range is equal to R1 plus R2 plus R3.
What is a kwh multiplier?
The basic unit of electric energy equivalent to one kilowatt used for one hour. For electric meters, this is the ratio of the customer’s total load to the amount of the load flowing through the meter. Residential, farm and small commercial meters usually have a multiplier of one.
What is difference between shunt and multiplier?
A Shunt is a passive element, usually resistive, that is used to bypass current around another element, like a meter, that is not able to handle the full current flow. A Multiplier is an active element that amplifies a voltage or current to enable a less sensitive device or circuit to make use of it.
What is the use of range multiplier?
A multiplier is basically a resistor connected in series with the voltmeter as shown below. The main function of the multiplier is to limit the flow of current through the voltmeter in such a way that the deflection of the pointer should not exceed the full-scale deflection.
What is Money Multiplier example?
The Money Multiplier refers to how an initial deposit can lead to a bigger final increase in the total money supply. For example, if the commercial banks gain deposits of £1 million and this leads to a final money supply of £10 million. The money multiplier is 10.
