Video Transcript

in the first part of this question, we're going to kill Claire. The time constraint. Let's find this dog with the equipment no equals two RC were seized the contestants off the capacitor. Let's call it a question one writing the values for this RNC iniquity in one we will get, though, equals two 75.1 to play tennis for three. Micah into 25.0 multiplied by tennis part minus seeks federal. So this will give us toe equals two. One point did. Second, In part B of this question, we need to find that total charge The charge on the capacitor a time d equals Toto, that is, Do you at the time where this time equals Toto. In order to complete this cure, we ride the Formula Two equals to go not into 0.632 where the securities maximum store charging capacitor and it is equals toe seeing to see where this is the potential difference off the battery. Now, using this well, you we can write this equation has two equals toe see into 0.632 Now setting the values off the sea and into this equation. We will get two equals to 25.0 multiplied voters for money. Six. Ferrari into 1 to 12 10 World in tow. 0.632 This is a coastal to it was too. 1.90 multiplied Butters part minus focal. So end of the question.
