WebYou have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. WebV = I × R. This equation is specific to the voltage (V) across the resistance (R in ohms) being generated as a result of the resistance and current (I in amps) circulating through the resistance. As an example, a current shunt with resistance of 0.002 ohms and current of …
WebJun 9, 2011 · To calculate the shunt resistance required you meed to know the current rating of the meter (possibly 100mA) and the resistance of the meter (Possibly 50ohms) You can use a multimeter and ingenuity to find these values.Then it is simple to calculate the resistance of the shunt to give the meter FSD at 30amps. WebThe most common way to measure current is to connect the ammeter (a meter to measure current) or shunt resistor in series with the circuit. An ammeter or ammeter shunt is really nothing more than a highly accurate resistor. When we place a precision resistor across a circuit, a voltage drop will occur across it.
