Question

For the given carbon resistor, the resistance is \(2.4 \times 10^6 \, \Omega\). The sequence of colours in the strips provided on resistor is

• A. red, yellow and green
• B. red, yellow and blue
• C. brown, orange and green
• D. red, green and yellow

Hint:

Resistor colour code = first two digits + multiplier. Example: \(2.4 \times 10^6 \, \Omega \Rightarrow\) red–yellow–blue.

Answer 1

The Correct Option is B

Step 1: Recall resistor colour code.
Digits: black–0, brown–1, red–2, orange–3, yellow–4, green–5, blue–6, violet–7, grey–8, white–9.
Step 2: Apply to given resistance.
Value: \(2.4 \times 10^6 \, \Omega\).
- First digit (2) → red.
- Second digit (4) → yellow.
- Multiplier (\(10^6\)) → blue (6). So, colour code = red, yellow, blue.
Final Answer: \[ \boxed{\text{red, yellow and blue}} \]
