What resistance is to be used to convert a galvanometer that gives full scale deflection of 1 mA to read up to 10 Amperes?
Please show a picture, and show work!!! I need to understand this!!!
In order to increase range of galvanometer a shunt resistance having very small value must be connected across coil of galvanometer. Due to shunt excess current bypasses through it and this prevents galvanometer coil getting damage. For a given range value of shunt resistance should be 0.010001ohm.
