How much energy is given to 5 coulomb of charge passing through 12 V battery? 


Charge, Q = 5 C
Potential across the battery, V = 12 V

Energy given by battery = Charge x Potential difference  
                                     = 5 C  x  12 V
                                     = 60 J.

State Ohm’s law.

Draw a schematic circuit diagram consisting a battery, a plug key, an ammeter and a bulb all connected in series with a voltmeter connected in parallel with the bulb.

How much work is done in moving a charge of 2 C across two points having a potential difference 12 V? 

Name the law which gives relationship between the potential difference across a conductor and the current flowing through it.
