Compute each part of given question:
Question: A muscle cell approximates a right circular cylinder 10 cm long and 70?m in diameter. The specific capacitance of the membrane is 1?F cm-2.
Part A: What is the capacitance of the muscle membrane?
Part B: How much charge is separated by this membrane to give a potential of -85mV?
I known the correct answer but I need to know how to get that. Thanks!
