does galvanometer show the current of electrons or conventional current????
Answers
Answer:
If you connect the galvanometer in your circuit “correctly” (i.e. with the higher-voltage lead in the red connector and the lower voltage lead in the black connector), then the galvanometer will show positive conventional current. The more (imaginary) positive charges flow from the higher-voltage lead to the lower-voltage lead, the farther to the right the galvanometer indicator will swing.

Since the convention exists as it does, you might as well just wire it up correctly; it’s easy to remember that electron current is just conventional current with a minus sign.
