What equation is used to find the membrane voltage in a neuron?

eq1.  membrane voltage = membrane current x specific membrane
resistance x (1 - Exp ^ (-time/tau).

eq2.  membrane voltage = (1/capacitance) x (current x voltage/
resistance)

eq1 from "The Neuron cell and Molecular Biology" I.B. Levitan & L.K>
Kaczmarek, 3rd ed.
eq2 from Principles of Neural Science", Kandel, Schwartz, Jessell, 4th
ed

They both are talking about the patch clamp technique.

Thanks
