Hi, Thanks alot.
I saw the other thread in which you helped https://www.physicsforums.com/showthread.php?t=352782
I was a little unsure if the currents were correct due to the location of the voltmeter but I have discovered and you have confirmed the location doesn't matter in this case...
Homework Statement
A cell of unknown e.m.f. , ε , and internal resistance, r, is connected in series with a
variable resistor. A voltmeter is then connected across the terminals of the resistor.
When the resistor has a value of 16.0 Ω the voltmeter reads 1.20 V. When the
resistance is...
