Ohm's Law

• If a voltage applied across a conductor, the 'current' passing through the conductor will be directly proportional to the voltage V.                                                    

                                                            V ∝ I

                                                            V=IR

                   Where 'R' = resistance of the conductor.

                   Resistance ('R') based upon the material of the conductor.

• The Current "I=V/R"
• If in a circuit we keep the similar resistance but vary the voltage, the current will also vary.
• Generally, for a values of 'V' and 'R' OHM'S Law is "I=V/R".
• Where 'I' = amount of current through resistance 'R', that is connected across a Potential difference 'V'.
• Volt (V) is the specific unit of potential difference and Ohm (Ω) is for Resistance, therefore,                                                                                                                  Ampere=Volts/Ohms
• This Formula is to calculate the Amperes of Current through 'R', merely divide the voltage across 'R' by the Ohms of Resistance.
