A cell drives a current of 5A throuh a 1.6 resistor. When connected to a 2.8 resistor the current that flows in is 3.2A. Find the E and r for the cell

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

could you provide figure.

step-by-step explanation:

for volume, add base x height x width
