Final answer:

The function that models the charge on the circuit can be found by integrating the given differential equation. The solution to the differential equation is q(t) = Qe^(-t/τ), where Q is the initial charge on the circuit and τ is the time constant of the circuit.

Step-by-step explanation:

The function that models the charge on the circuit can be found by integrating the given differential equation. The differential equation is:

q′′ + R/L q′ + 1/(LC) q = 1/(L1)E(t)

Integrating this equation will give you an equation for the charge on the circuit as a function of time.

The solution to the differential equation is:

q(t) = Qe^(-t/τ)

Where Q is the initial charge on the circuit, τ is the time constant of the circuit, and t is time.
