Question

A carbon resistor has coloured rings in the order red red orange and gold find the resistance

Answer 1

Answer:

According to colour code of carbon resistors, red stands for 2, yellow for 4, blue for 6 and silver stands for 5%.

First and second band represents the first two significant figure of resistance.

Third band represents the power raised to 10 in the value of resistance.

Fourth band represents the tolerance.

Thus resistance of given carbon resistor is 24×10

6

Ω

Tolerance in the resistance is 10%.

Thus resistance is 24×10

6

Ω ±10%
