Charge flows between two ends of a conductor when
Equal and same type of charges are present at the two ends
Different electric potentials exist at the two ends of a conductor
The potential difference between the ends is zero
Same electric potential is present at the two ends
Current is the flow of
Matter.
Electrodes.
Protons.
Charge.
A cell converts
Electrical energy into chemical energy.
Chemical energy into electrical energy.
Magnetic energy into electrical energy.
Electrical energy into mechanical energy.
The process of chemical decomposition of a solution on passing electric current through it is known as
Electroplating.
Electrolysis.
Hydrolysis.
Diffusion
Metals are good conductors because
Outer electrons are loosely bound to the atom
Outer electrons are strongly bound to the atom
Inner electrons are loosely bound to the atom
Protons can detach from the nucleus and conduct electricity
The electrode at which terminal get plated during electroplating?
Positive.
Negative.
Neutral.
Either positive or negative
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.
Which of the following present in the lemon juice acts as electroplate?
Sulfuric acid.
Nitric acid.
Hydrochloric acid.
Citric acid.
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.
In a cell, electrons move from:
Positive electrode to negative electrode.
Negative electrode to positive electrode.
Electrones do not move and only negative charge moves from one place to another place.
