1. The problem statement, all variables and given/known data A block of carbon is 3cm long and has a square cross section whose sides are .5cm long. A potential difference of 8.4V maintained across its length. a)What is the resistance of the block? b)What is the current in this resistor? 2. Relevant equations R=pL/A where p is resistivity 3. The attempt at a solution I'm fairly certain i can solve this problem right quick if I could understand what exactly the block looked like. The description just doesn't make sense to me. I'm not sure if you can draw pictures on this or not but a picture would be helpful if someone can make one. Thanks.
