A carbon resistor is marked in green, red, and orange bands. The approximate resistance of the resistor is
Open in App
Solution
The correct option is B
Resistor colour code of green is 5, and that of red is 2. The first two numbers indicate significant figures of the resistance in ohm. The third band indicates the decimal multiplier. So, the total resistance of the given problem is
