Question when the pointer of galveno meter travel toward right or sometime..towrds left..for what reason it towards right or left??
Answer Direction of current. To plus means current is going into the plus terminal, etc.
The pointer is driven by a coil in a magnetic field and the force generated is a function of the direction and magnitude of the current. If you reverse the connections to the galvo meter it will reverse the current and send the needle the opposite direction.
