Question 1114768: Please help me answer the following question:
1.) The differential equation governing current flow, i(t), in a
series RA circuit, is given by:
++iR+%2B+A++%28di%2Fdt%29+=+t+ , t ≥ 0, i(0)= 0
where R and A are constants. Use an appropriate technique to
find the current i(t)

A(di/dt)=t-iR
di/dt=(1/A)(t-iR)
i=(1/2A)(t^2-2iRt)

What is an RA circuit?
Do you mean RC? RL?
