  • a)
    Is halved
  • b)
    Is doubled
  • c)
    Remains unchanged
  • d)
    In quadrupled
Correct answer is option 'C'. Can you explain this answer?

A 10 ohm resistance, 5 mH coil and 10μF capacitor are joined in ser...
Explanation:
This is a series RLC circuit where the resonance frequency is given by the formula:

Resonance frequency (fr) = 1 / (2π√(LC))
Where L is the inductance and C is the capacitance in the circuit.

Effect of changing resistance:
When the resistance in the circuit is halved, it does not affect the inductance (L) or capacitance (C) of the circuit. Therefore, the resonance frequency remains unchanged.
Therefore, the correct answer is option C. Remains unchanged.
