Six light bulbs are connected in parallel to a 9 v battery. each bulb has a resistance of 3 ω. what is the potential difference across each bulb?

9Volts each

Explanation:

Note that for a parallel connected loads in a circuit, same voltage is passed through the loads but different current flows through them. Therefore each loads will possesses the same voltage as the voltage of the battery and since they are all connected to it battery directly i.e 9V

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

conservation of mass

mass before something happens = mass afterwards
