Fill in the colour codes on these blank resistors to show the given resistance or write the colour of each band above if you don't have coloured pencils or pens. a) 200 Ω Tolerance of 5%. b) 550 Ω Tolerance of 10%.

The first digit is 2, which corresponds to the color Red.

The second digit is 0, which corresponds to the color Black.

To get $200 \, \Omega$ from the first two digits (20), we need to multiply by $10^1$. The multiplier $10^1$ corresponds to the color Brown.

A tolerance of $5\%$ corresponds to the color Gold.

The color codes are:
Band 1: Red
Band 2: Black
Band 3: Brown
Band 4: Gold

$330 \, k\Omega = 330 \times 1000 \, \Omega = 330000 \, \Omega$.

The first digit is 3, which corresponds to the color Orange.

The second digit is 3, which corresponds to the color Orange.

To get $330000 \, \Omega$ from the first two digits (33), we need to multiply by $10^4$. The multiplier $10^4$ corresponds to the color Yellow.

A tolerance of $10\%$ corresponds to the color Silver.

The color codes are:
Band 1: Orange
Band 2: Orange
Band 3: Yellow
Band 4: Silver
