Question

Brown,black and gold is the color band on the resistor,find its resistance?

• A. $10\times {10}^{-2}\Omega$
• B. $1\Omega$
• C. $100\Omega$
• D. $10\times {10}^0\Omega$

Answer 1

The correct option is B $1\Omega$

The first two colours are brown and black.

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

And, brown colour signifies $1$, and black colour signifies $0$.

And for multiplier the third colour is considered which is here gold meaning $0.1$.

Hence, resistor is $10\times 0.1=1\Omega$

Answer-(B)
