In this episode of "No Talk Only Do", I go through 4 practice problems related to charging capacitors - no talking involved - just some energizing backing tracks
Timeline for Questions
00:02 Question 1: Determine the equations for voltage across the capacitor (vc), voltage across the resistor (vr), and current through the capacitor (ic). Also calculate the values of vc, vr and ic at 15 ms
01:21 Question 2: How long will it take the capacitor to fully charge?
01:45 Question 3: How long will it take to charge the 0.01F capacitor to 5V?
02:45 Question 4: An alarm countdown is started when a switch closes on an RC circuit. What R and C values do you need for it to take 10 seconds to charge the capacitor to 9V (and subsequently sound the alarm)?
