Two Electrodes in voltaic cell are
1 point
Zinc,Graphite,
Graphite
Zinc, Copper
Copper, Iron​

Answer 1

Answer:

There are two electrodes in a voltaic cell, one in each half-cell. The cathode is where reduction takes place and oxidation takes place at the anode. ... Metal ion Mn+ from the solution may collide with the electrode, gaining "n" electrons from it, and convert to metal atoms. This means that the ions are reduced.

Answer 2

Explanation:

A planar loop of any shape behaves as a magnetic dipole. The dipole moment of current loop (M)= ampere turns (nI) × area of coil (A) or M=nIA M = n I A . Magnetic dipole moment is a vector with direction from S pole to N pole or along direction of normal to planar area.
