Question:

Which of the following parameter in the series LCR circuit is analogous to driving force F in mechanics?

Inductance L

Capacitance C

V0L

VoltageV0

Solution:

In mechanics, the equation for forced oscillations is: m(d²x/dt²) + b(dx/dt) + kx = F. For LCR series circuit, the equation is: L(d²q/dt²) + R(dq/dt) + q/C = V₀. Thus, the parameter analogous to driving force is V₀.
