Question

The colour code of a resistor is brown, black and brown. Then the value of resistance is _____

• A. $10$ $\Omega$
• B. $100m\Omega$
• C. $0.1k$$\Omega$
• D. $1000$ $\Omega$

Answer 1

The correct option is C $0.1k$$\Omega$

First two colours says about significant digits of resistance and the third colour gives multiplier.

Brown colour gives digit $1$, brown colour gives digit $0$ and for multiplier brown colour gives ${10}^1$.

Hence, resistance $=R=10\times {10}^1=100\Omega$

$⟹R=0.1k\Omega$

Answer-(C)
