Current is the flow of
Matter
Electrons
Protons
Charge
When an electron moves from negative electrode to positive electrode:
Negative charge moves from negative electrode to positive electrode.
Positive charge moves from positive electrode to negative electrode .
No charge flows from either electrode to other electrode.
Both A and B.
When the ends of metal wire are not connected to a battery:
electrons move from positive electrode to negative electrode
electrons move from negative electrode to positive electrode
electrons move in random directions
protons move in random direction in such a way that their net movement in a unit volume is zero
The process of chemical decomposition of a solution on passing electric current through it is known as
Electroplating.
Electrolysis.
Hydrolysis.
Diffusion
Materials which allow electric current to pass through them are called
Conductors.
Insulators.
Semiconductors.
None of these.
A cell converts:
Electrical energy into chemical energy.
Chemical energy into electrical energy.
Magnetic energy into electrical energy.
Electrical energy into mechanical energy.
Electrons move from positive electrode to negative electrode.
Electrons move from negative electrode to positive electrode.
Electrons move in random directions.
Protons move in random direction in such a way that their net movement in a unit volume is zero.
Insulators
Conduct electricity at room temperature
Conduct electricity only at low temperature
Do not conduct electricity
Conduct electricity
