Multiplier Resistance in Ohmmeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Multiplier Resistance = (Potential Difference/Current)-Galvanometer Resistance
R_mul = (V/I)-R_gal
This formula uses 4 Variables

Variables Used

Multiplier Resistance - (Measured in Ohm) - Multiplier Resistance is the resistance of series resistor which is used for increasing working range of the meter.
Potential Difference - (Measured in Volt) - Potential Difference also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field.
Current - (Measured in Ampere) - Current is the rate of flow of charge through a cross sectional area.
Galvanometer Resistance - (Measured in Ohm) - Galvanometer Resistance refers to the opposition offered by the galvanometer to the current passing through it.

STEP 1: Convert Input(s) to Base Unit

Potential Difference: 18 Volt --> 18 Volt No Conversion Required
Current: 2.1 Ampere --> 2.1 Ampere No Conversion Required
Galvanometer Resistance: 4.25 Ohm --> 4.25 Ohm No Conversion Required
