Examine the Doppler effect illustration above. Assume the red dot is a police car with it's siren on. Which direction is the police car traveling?
A)
down
B)
left
C)
right
D)
up

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

see earlier answer

pretty sure it's false
