An 'RC charging circuit' is shown in the figure below: R Assume that C1 = C and that C: = 2C. In other words, capacitor 2 has twice the capacitance compared to capacitor 1. Determine an expression for the time it takes capacitor C: to charge up to 90343 of its final value. Tour expression should he in terms of R and C. 1. Getting Started: State the important information and summarize the problem. If possible, include a diagram. Note any assumptions you're making. 2. Devise Plan: Devise a plan of attack before diving into the solution. Break down the problem into smaller, manageable segments. Identify which physical relationships you can apply. 3. Execute Plan: Carry out your plan, explaining each step. The argument should be easy to follow. Articulate your thought process at each step (including roadblocks). Any variables should be clearly defined, and your diagrams should be labeled. 4. Evaluate Solution: Check each solution for reasonableness. There are many ways to justify your reasoning: check the symmetry of the solution, evaluate limiting or special cases, relate the solution to situations with known solutions, check units, use dimensional analysis, and/or check the order of magnitude of an answer. Note: If you got stuck in the
