It is often useful to take a cell operating at a certain solar irradiance and temperature and calculate its electrical output characteristics (i.e. voltage-current (V-I) curve). It is also desirable to perform these calculations using commonly available manufacturer data, e.g. open circuit voltage, short circuit current, voltage and current at maximum power point. In this article,...")

Death from electrical shock results from ventricular fibrillation, paralysis of the respiratory centre or a combination of the two. w:Ventricular fibrillation is a condition wherein the heart quivers but does not beat.

An electric current is a flow of electrons; we can compare the flow of electrons in a wire to the flow of water in a pipe. Today we can read about electronics and electrons in newspapers, magazines, and many schoolbooks. However, the practical electrician needs to know more about electrons than a mechanic or machinist does. Therefore, let us see how electric current flows in a...")

All material impedes the flow of electrical current to some extent. The amount of resistance depends upon composition, length, cross-section and temperature of the resistive material.

A force is required to get water to flow through a pipe. This force comes from either a water pump or gravity.
