SUMMARY

The discussion focuses on solving the differential equation for capacitor charging, represented as E = R(dQ/dt) + (Q/C). The user seeks assistance in manipulating the equation to isolate terms for integration. A key suggestion provided is to divide the equation by dQ, rearranging the terms to facilitate integration, ultimately leading to the solution for Q(t).

I'm trying to solve this:

[tex]E = R\frac{dQ}{dt} + \frac{Q}{C}[/tex]

from here

You might recognize this as the charging equation for a capacitor

I'm guessing I need to try and get (1/q)dQ or similar somewhere to get the lnQ

but I cannot seem to get the right manipulation

Thanks
Thomas

for example,
divide the equation by dQ and write the terms with dQ and dt each to another side of the equation. Integrate both sides and you will be able to find Q(t)
