Problem
A designer needs an RC circuit that reaches 63% of its final charge in 5.0ms using a single 1.0μF capacitor. Available resistors follow the E12 series (10 Ω, 12 Ω, 15 Ω, … up to 8.2 MΩ). Identify the smallest standard resistor value that will meet or exceed the required timing specification.
