In the given figure of a resistor, the value of carbon resistance is
Correct answer: C. 1500±5 Ω
- A. 360 ± 5% Ω
- B. 970 ± 5% Ω
- C. 1500±5 Ω
- D. 2800 ± 5% Ω
Explanation
The color bands on a resistor are interpreted as follows: The first band (Brown) represents the first significant digit, which is 1. The second band (Green) represents the second significant digit, which is 5. The third band (Red) represents the multiplier, which is 100 (since red corresponds to 10^2). The fourth band (Gold) represents the tolerance, which is ±5%. Using these color bands, we can calculate the resistance value: Resistance = (First digit * 10 + Second digit) * Multiplier = (1 * 10 + 5) * 100 = 1500 Ω Therefore, the correct answer is: c. 1500±5 Ω

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
