Homework Equations
The Attempt at a Solution
For the ammeter resistance i chose to find the difference in the voltmeter reading in the two circuits. that difference is the p.d. across the ammeter, right?
but i don't know which ammeter reading to use now. in fact i think i have been on the wrong track all along.
perhaps someone can give some hint for me to get started?
