PHYS 1302W Lecture Notes - Lecture 1: Capacitor
Document Summary
Uncharged c. the book uses a lowercase i to represent changing current, and an uppercase i to represent constant current. Immediately after closing the switch, q is still negligibly small 0. As time goes on, q increases and i decreases. It sets the rate of charging or discharging. Negative sign since it is a discharging capacitor. Although the average voltage of v(t) is zero, power is consumed in a resistive element for both positive and negative values of v. the effect is equivalent to a d. c. voltage of. In the us, vrms is nominally 120v and equals the maximum value of v(t) divided by (2) Power to s house typically involves 3 wires, 2 hots and one neutral. Hot #1 is red, hot #2 is blue (180 degrees out of phase) and hot #3 in green. Each 120 v circuit in the house taps off one of the hots and the neutral.
