APFIVE Potential Difference in Parallel Circuits
In a circuit with two parallel branches, each containing a resistor and connected to a 9 V battery, what must be true about the potential differences across each resistor according to Kirchhoff’s Loop Rule?
A
The potential differences depend on the ratio of resistances
B
Each resistor has a potential difference of 9 V
C
The potential difference is 4.5 V across each resistor
D
