Ohm''s law states that the current flows through a conductor at a rate that is proportional to the voltage between the ends of this conductor. In other words, the relationship between voltage and current is constant: I/V = const. The Ohm''s law formula can be used to calculate the resistance as the quotient of the voltage and current.

When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.

A short circuit in a battery is bad news: the chemical energy stored in the battery is lost as heat, rather than being used to power a device. In this example, the short circuit current is predicted to be modest compared to the total battery capacity, so the operating cell voltage is not significantly perturbed by the local short circuit

Short Circuit Definition. If the resistance or impedance of the load is bypassed or shorted, then, according to Ohm''s law, an abnormally high current will flow through the circuit.This situation is called a short circuit.. Depending on the remaining resistance or impedance of the circuit, the short-circuit current could be up to 30 times as high as the normal current.
