Yogita Ingle 5 years, 8 months ago

Force that resists motion of one body over another with which it is in contact.
Denoted by f_k
As motion starts, f_svanishes and f_k appears
Kinetic friction is Independent of the area of contact and velocity of the body
It varies with Normal reaction, N

f_k ∝ N

f_k = constant * N

f_k = μ_k N; μ_k is the coefficient of kinetic friction

Yogita Ingle 6 years ago

Electric current is measured as the rate of flow of charge. What it basically means is that it is how much charge that is flowing with respect to time.

One can also define current electricity as the movement of electrical energy from one place to another for the utilisation is termed as an Electric current or Current Electricity. Charges in motion establish an electric current.

If you consider a charge of 20Coulomb flowing per second. Then the current will be 20Coulomb/sec.

The symbolic denotation of electric current is I.
