This article focuses on single-cell electrophysiology and introduces the fundamentals of electrophysiological investigation by describing the ionic basis of action potentials and the different ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...

This equation can be used to calculate what the output might be from a particular transformer, or to work out how to design a transformer to make a particular potential difference change: ...
