<ul><li>Current is the flow of electrons and can be measured by the amount of electrons passing through a material per second.</li><li>The relation between charge (Q) and electric current (1) is given by 1/t0 = t1/t, where t0 and t1 are the total and transfer time, respectively.</li><li>An electric potential, also known as potential difference or voltage, exists between two charged particles in a circuit, causing the flow of current from higher to lower potential.</li><li>The symbol for potential difference is V and it is measured in volts.</li></ul>
