How do I solve this, it's a complex circuit and I don't know how to do it​

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

option number c is the right answer.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
