An RL circuit has L=5, R = 200, Vin =100t. Suppose the initial current through the circuit is I(0)=1. a) find the current through the inductor. b) sketch it. Find the voltage through the Inductor. c) Sketch it I feel like it know how to do this but I am getting a linear function which doesn't...

yes i don't know how to get there − 3 ln − 20 x + ln − 10 x = − 2 ln − 1 x − ln 800 −3ln⁡−20x+ln⁡−10x=−2ln⁡−1x−ln⁡800 finding c will get me the initial temp bc t will cancel out k when t is 0.Reference https://www.physicsforums.com/threads/find-this-initial-temperature.887268/

Suppose that you take a thermometer outside where it is 100°. T(5min)=80° T(15min)=90° What is the initial temp of the thermometer? Given equation dT/d t= k(T-Te) Derived Equation ⌠(T-Te)^-1 (dT/dt)dt =⌠ kdt ln(T-Te)=kt + c T=ce^kt + Te so i basically got the answer by knowing c...
