Final answer:
The expected resistance range for a resistor marked as 1800 Ω ± 15% would be between 1530 Ω to 2070 Ω, calculated by adding and subtracting 15% of the nominal value from itself. This range corresponds to option a.
Step-by-step explanation:
The question involves calculating the tolerance range for a resistor marked with a nominal value and a percentage deviation. Given a resistor marked as 1800 Ω ± 15%, the range of resistance is calculated by taking 15% of 1800 Ω, which amounts to 270 Ω. The expected range would therefore be the nominal value plus and minus this deviation. Calculating both ends of the range:
- Minimum resistance: 1800 Ω - 270 Ω = 1530 Ω
- Maximum resistance: 1800 Ω + 270 Ω = 2070 Ω
Therefore, the expected resistance range for this resistor would be between 1530 Ω to 2070 Ω, which corresponds to option a.
