Potential diffrence (V) = ? Electric Current is a scalar quantity. Combination of Resistors Since, the electric energy is supplied for time ?, thus, after multiplying both sides of equation (ii) by time t, we get, Flow of electric charges is called electric current, i.e,  I = Q / t. To know more about Electric Current, visit here. When a glass rod is rubbed with silk, electrons move from glass rod to silk therefore, the glass rod acquires a positive charge as it becomes deficient of electrons and silk will acquire negative charge as the amount of negative charge in it increases. Electricity and a few terminologies. → An electric current-carrying wire behaves like a magnet. They have free mobile electrons. A copper wire has diameter 0.5 mm and resistivity of 1.6 × 10–8 Ω m. What will be the length of this wire to make its resistance 10 Ω? 1A = 1C Therefore, V = \(\frac { W }{ Q }\) Electricity And Magnetism.
