1. Kirchhoff’s current law

2. Nodes , branches and loops

• OHM’S LAW

• At constant temperature, the current flowing through a conductor is directly proportional to the potential difference in volts across the ends of the given conductor and inversely proportional to resistance (R) in ohms between the ends of the same conductor.

                                          I α PD/R α volts/ohm

          

                                                       V = I x R                  where, V = voltage

                                                                                                     I = current

                                                                                                     R = resistance

• KIRCHHOFF’S CURRENT LAW

• KCL states that “the total current entering the node is equal to the total current leaving the node”.
