A. 2
B. 3
C. 4
D. 5
A. Becomes double
B. Remains same
C. Becomes half
D. First increases then decrease because of the curvilinear graph
A. Through direct collision
B. Through electrostatic attraction
C. Through electrostatic repulsion
D. All of above
A. Protons
B. Electrons
C. Metal atoms
D. Metal ions
Electric current in a solid metal conductor is caused by the movement of electric charge. An electric current is the flow of electric charge. An electron current, the flow of electrons, contributes to an electric current since the electron ‘carries’ negative electric charge.
