MY NOTES ASK YOUR TEACHER Which of the following are characteristics of series circuits? Select all that apply. C] There are multiple paths for current to follow through the circuit. C] The voltage is divided among all devices in the circuit. D There Is only one path for current to foilow through the circuit. C] If one device in the circuit stops allowing current to flow, all other devices in the circuit will also stop functioning. D The voltage across each device must be the same. D 111e same amount of current flows through all devices in the circuit. Need Help? [-r'1l} Points] OBINPHY58 T.

O The 13 A fuse would be safer. since it is lower than the 23 A original. 0 The 30 A fuse wOuld be safer, since It Is large enough to handle 23 A, C) More information is needed. The 18 A fuse might be better because it is closer to the 23 A original or the 30 A might be better because it seems to have enough capacity. Need Help? 5. [410 Points] DETAILS OBINPHY58 T.P.001. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER (a) Two charged particles exert an electric force of 30 N on each other. What will the magnitude of the force be if the distance between the particles is reduced to onefourth of the original separation? .. N (b) If the original distance between the particles is now restored how much larger would the charge on either one of the particles have to become to yield the same force that was present when the particle separation was only one fourth its original \\l'alue'rI times Need Help
