Current Electricity | Electric Current ⚡ (Class 11 Physics)

Current Electricity deals with the flow of electric charge in conductors and the factors affecting it.

Electric Current is defined as the rate of flow of charge:
I = \frac{Q}{t}
Where,
I = current (ampere, A)
Q = charge (coulomb, C)
t = time (second, s)

One ampere means:

1 coulomb of charge flowing per second through a cross-section of a conductor.

Main topics covered in this chapter:
1. Electric Current and Drift Velocity
2. Relation between current and drift velocity
I = nqAv_d
3. Ohm’s Law
V = IR
4. Resistance and its factors
R = \rho \frac{L}{A}
5. Electrical Energy and Power
P = VI = I^2R = \frac{V^2}{R}
6. Combination of resistors (Series & Parallel)
7. Electromotive Force (EMF) and Internal Resistance
V = E - Ir
8. Kirchhoff’s Laws
9. Wheatstone Bridge
10. Meter Bridge and Potentiometer
11. Heating effect of current (Joule’s law):
H = I^2Rt
