6. ELECTRIC POTENTIAL The unit of electric potential is the volt (V) where one volt is one joule per coulomb. One volt is defined as the difference in potential between two points in a conductor which, when carrying a current of one ampere, dissipates a power of one watt, i.e. [email protected] 6

7. ELECTRIC CURRENT [email protected] 7

8. ELECTRIC POWER The unit of power is the watt (W) where one watt is one joule per second. Power is defined as the rate of doing work or transferring energy. Energy = power × time Power = voltage × current [email protected] 8

9. Ohm’s LAW Ohm’s law states that the current I flowing in a circuit is directly proportional to the applied voltage V and inversely proportional to the resistance R , provided the temperature remains constant. [email protected] 9
