Question

A $200\Omega$ resistor has a certain color code. If one replaces the red color by green in the code, the new resistance will be

• A. $100\Omega$
• B. $400\Omega$
• C. $500\Omega$
• D. $300\Omega$

Answer 1

The correct option is C $500\Omega$

When red is replaced with green, the first digit changes to $5$, so new resistance will be $500\Omega$.
