Question
In the diagrams, resistors R1 and R2 are shown in two different connections to the same source of emf E that has no internal resistance.
How does the power dissipated by the resistors in these two cases compare?
1. It is different for each connection, but one
must know the values of R1 and R2 to know
which is greater.
2. It is different for each connection, but one
must know the values of E to know which is
greater.
3. It is greater for the parallel connection.
4. It is the same for both connections
5. It is greater for the series connection.
Explanation / Answer
3. It is greater for the parallel connection.
