Answer:
V= 57.5 V
Explanation:
- If the resistors are in the linear zone of operation, the potential difference across them, must obey Ohm's law:
- For the 6.0 Ω resistor, if the potential difference across it is 15 V, we can find the current flowing through it as follows:
- In a series circuit, the current is the same at any point of it, so the current through the battery is I = 2.5 A
- The equivalent resistance of a series circuit is just the sum of the resistances, so, in this case, we can write the following equation:
- Applying Ohm's Law to the equivalent resistance, we can find the potential difference through it, that must be equal to the potential difference across the battery, as follows:
