Can someone help me figure out questions 6 and 7? im learning physics.
1 Answer
Explanation:
We have to assume that the 3 bulbs are equal and the 2 voltage sources are equal. It would be unfair otherwise, sorry, but I am generally suspicious.
The next question's explanation should make it more clear.
the circuit with less resistance will have more current.
The question did not ask for this, but here is some extra discussion: Since
the circuit with higher current will use energy faster -- meaning it will give more light energy. In fact, the one bulb in A will provide more light energy than the total provided by the 2 bulbs in B.
I hope this helps,
