Answer:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
A one watt bulb consumes 1 joule of elecrical energy every second. To calculate the total amount of energy consumed in your example, multiply (1 joule/second) x (30 watts) x (5 minutes) x (60 seconds/minute) = 9000 joules.
