KCL, KVL, Conservation of charge and Energy and introduction to Galvanometer
KCL, KVL, Conservation of charge and Energy and introduction to Galvanometer-
KCL is simply based on conservation of charge. That is charge cannot accumulate at a junction.
KVL is based on conservation of energy. That is energy supplied by the source will be equal to the energy consumed by the circuit elements
$\sum V=0$
Galvanometer-
It is an instrument used to detect small current passing through it by showing deflection.
Example for types of galvanometers are
moving coil galvanometer
moving magnet galvanometer
