Electrical analogous quantity for dash-pot in force-current analogy is

Electrical Engineering XYZ MCQs

Electrical analogous quantity for dash-pot in force-current analogy is:

  1. Capacitance
  2. Inductance
  3. Conductance
  4. Resistance

Correct answer: 4. Resistance

Explanation:

The force-current analogy is a method used in electrical engineering to analogize mechanical systems with electrical circuits. In this analogy, different mechanical elements such as mass, spring, dashpot (viscous friction element), etc., are represented by electrical elements such as capacitors, inductors, resistors, etc., respectively.

When considering the dashpot, which represents viscous friction in a mechanical system, its analogous electrical quantity is the resistor.

Therefore, the correct answer to the multiple-choice question is:

  • Resistance

Good to know:

  • Capacitance is analogous to mechanical compliance or flexibility.
  • Inductance is analogous to mechanical inertia or mass.
  • Conductance is analogous to mechanical compliance in certain cases, but it’s not directly associated with the dashpot.
  • Resistance is analogous to mechanical damping or resistance, which aligns with the function of a dashpot in a mechanical system.
