Finding V & I in Equivalent Circuits: KVL & KCL Methods Explained

Click For Summary
The discussion focuses on solving for voltage (V) and current (I) in equivalent circuits using Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). The original poster solved the problem but expressed confusion about whether to express the answers in terms of time (t) or to find specific values for t. It is clarified that t is an independent variable, meaning it will naturally appear in the solution. The answers can remain in terms of t, as it represents a point in time chosen by the user. Understanding that t is not a fixed value but a variable is crucial for interpreting the results correctly.

Homework Statement


the problem asks to find V & I so the two circuits are equivalent ,,

i solved it by using KVL & KCL but my answer is in term of t ! my question is Do they really have values ? i mean ,do i have to find t firstly ? or just write them in term of t only ?

thanks

t is an independent variable and so will appear in your answer. t is measured from any point in real time you choose.
