Expert Solution

Step 1

In four band colour coded resistor, first and second band colour are use to give the digit of the resistor, third colour band is use to calculate the multiplier and the last band is use to calculate the tolerance.

1: For resistor 1,

The first band is white, the digit associated to white is 9.
The second band is brown, the digit associated to brown is 1.
The third band is brown, the multiplier associated to brown is 10.
The fourth band is gold, the tolerance associated to gold is ±5%.

Hence, the resistor 1 is 910 Ω, ± 5%.

2: For resistor 2,

The first band is brown, the digit associated to brown is 1.
The second band is red, the digit associated to red is 2.
The third band is red, the multiplier associated to red is 100.
The fourth band is gold, the tolerance associated to gold is ±5%.

Hence, the resistor 2 is 1200 Ω, ± 5%.
