close the switch and store energy to open the switch
How Does a Light Switch Work?
A four-way switch works by toggling the electrical pathway back and forth between the two three-way switches. It can reverse a pathway that is complete to turn the light OFF or reverse a pathway that is broken to turn the light ON. Essentially, it serves to open or close an electrical pathway.
Read MoreSolved Two capacitors C_1 and C_2 (where C_1 > C_2) are
Here''s the best way to solve it. Two capacitors C_1 and C_2 (where C_1 > C_2) are charged to the same potential difference V_0, but with opposite polarity. The charged capacitors are removed from the battery, and their plates are connected as shown in Figure 26.10a. The switches S_1 and S_2 are then closed as in Figure 26.10b.
