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 200 \(\Omega\) resistor has a certain color code. If one replaces the red color by green in the code, the new resistance will be :
Show Hint
200 ohm = red, black, brown (2, 0, multiplier 10). Red is the first band; green stands for 5.

- \(500\ \Omega\)
- \(100\ \Omega\)
- \(200\ \Omega\)
- \(300\ \Omega\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Colour code values: black 0, brown 1, red 2, orange 3, yellow 4, green 5.
A resistor of 200 \(\Omega\) = \(20\times10^{1}\) \(\Omega\) has bands red (2), black (0), brown (multiplier \(10^1\)).
The only red band is the first digit band. Replace it by green (5): digits 5, 0 and multiplier \(10^1\).
New resistance \(= 50\times10 = 500\ \Omega\).
Answer: (1) \(500\ \Omega\)
A resistor of 200 \(\Omega\) = \(20\times10^{1}\) \(\Omega\) has bands red (2), black (0), brown (multiplier \(10^1\)).
The only red band is the first digit band. Replace it by green (5): digits 5, 0 and multiplier \(10^1\).

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
