The study of electric current takes you to Ohm’s law and Kirchoff’s Laws for circuits. Interesting animations help to get a feel of resistances, series and parallel circuits, and circuits with junctions. A section on capacitors charging and discharging, is included here too.
Following topics are covered:
1) Introduction- what is Electric Current (Flow of electrons)
2) Drift current and speeds
3) Resistors and Resistances
4) Resistors: Colour bands for identification
5) Ohm’s Law
6) Energy Transfer in a circuit- Heating up of resistors
7) Combining Resistors in Series and Parallel
8) Kirchoff’s Law, Junction Law
9) The LOOP Law
10) Wheatstone Bridge
11) Solved Problems
