Question

Blue,green,yellow and yellow is the color band on the resistor,find its resistance?

• A. $(75\times {10}^4)\Omega \pm 5$%
• B. $(65\times {10}^4)\Omega \pm 5$%
• C. $(52\times {10}^4)\Omega \pm 5$%
• D. $(65\times {10}^4)\Omega \pm 10$%

Answer 1

The correct option is B $(65\times {10}^4)\Omega \pm 5$%

The first two colours are blue and green.

For first two significant digits we need to consider digits signified by first two colours.

And, blue colour signifies $6$, and green colour signifies $5$.

And for multiplier the third colour is considered which is here yellow meaning ${10}^4$.

And, for tolerance , fourth colour is given yellow meaning $5\%$.

Hence resistance is $(65\times {10}^4)\Omega \pm 5\%$

Answer-(B)
