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

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
