Describe with the aid of a diagram, an absolute method of measuring current.
Describe with the aid of a diagram, an absolute method of measuring current.
Current balance is based on principles of moments
The apparatus setup is as above, AB = AF, length BC = L and the current through the wire is A
The magnets provide a uniform magnetic field, B, perpendicular to wire BC.
At equilibrium when the frame BCEF is balanced
The force exerted on the wire = weight of the mass
BIL = Mg
I = Mg/BL
Sources of error
- Accuracy of length L
- Rigidity of the frame
- To avoid overheating, the current should be switched off as soon as measurements have been taken.
- Shield the set-up from the disturbance of wind.
