Ohm's Law, Resistivity & Temperature

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

Show answer and solution

Answer: (a)

  1. 200 Ω=20×101200\ \Omega = 20 \times 10^1: Red (2), Black (0), Brown (×10\times 10).
  2. Replace red by green (5): 50×10=500 Ω50 \times 10 = 500\ \Omega.
  3. So the answer is (a) 500 Ω500\ \Omega.
