1. Given t1/2 to be 0.0137 seconds, how long should it take to reach 87.5% of maximum charge?

Question

2. Let's say you measure t1/2 to be 0.0137 seconds and the resistance in the circuit is 99 Ohms. Then what is the capacitance in micro Farads?

3.q = qmax(1 - e -t / τ)
Using this equation one can see that when t = τ*ln2 that q = 0.5 qmax. Or, that q equals 50% of qmax.
What is the percentage of qmax when t = 4 * tau * ln2?

4.The following equation is for the next question.
t½ = τ ln2 = RC ln. Given a resistance of 99 Ohms and a capacitance of 200micro Farads,
what is t½?

Answer 1

What is t1/2?
