Oh sorry 60 volts. I took the slope of the line and then inverted it to get the result. m=y_2-y_1/x_2-x_1=.8-.3/45-115=.5/30=1/60, 1/E=1/60, E=60 volts, so E=I(R+r), 1/I=1/E(R+r) r=(E/I)-R r=(60/(1/0.3))-15 r=(60*0.3)-15 r=3 ohms

Well I find the slope of 1/E to be about 1/60, so E would be 60 I think?

I mean use the y-intercept to find the r value?

Wait, so we could think of the internal resistance of the battery as the y-intercept?

Hello I am currently a student and I am joining this forum because I am severely lacking knowledge in science. Thank you

Homework Statement Students are given some resistors, a battery with internal resistance, and an ammeter. They are asked to determine the emf e and internal resistance of the battery using just this equipment. Working with the circuit shown at right, they insert each resistor into the circuit...
