Finding Potential Difference in a Series Circuit
In the circuit above, if the current in the circuit is I, then the potential difference across each of the resistor is
Find the potential difference across each of the resistors in the diagram above.
The potential difference across the 2 resistors, V = 12V
The equivalent resistance of the 2 resistors, R = 2 + 4 = 6Ω
Current pass through the 2 resistors,
For resistor R1,
For resistor R2
