What happens when an electric charge passes through a circuit?

The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.

the electric currents travel through and lead to the object it's flowing into

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
