Question

1500 W 60 V 20 W 128 W 22 W Fuse Figure 2: Picture of the setup in problem 5. 4.) Which configuration of charge has more electric potential energy? (a.) an equilateral triangle (all sides the same length 1) with positive charge +q at each corner or (b.) a square (all sides have length l) where three corners are occupied by +q charges and the final is occupied by charge Show all work. (pun sort of intended "hint hint*) 5.) A circuit is fitted with a fuse with a current threshold of 40A, will it blow (see Fig. 2)? Show all work.
