How does current exist wen voltage is zero in short circuit?

According to Ohm's Law, V = I*R, where V = voltage (volts), I = current (amps), and R = resistance (ohms). Mathematically speaking, when you have a short circuit, resistance is said to be zero, as well as voltage is equal to zero, therefore zero divided by zero is infinity. In a few words, you can't have infinite current but that means current exists in a fairly large quantity in a short circuit which is why equipment burns out with short circuit.


The voltage in a lightbulb is given by the equation V IR. In this equation V is the voltage I is the current and R is the resistance. What is the current in a lightbulb with a voltage of 10.0 V and a?

To find the current in a lightbulb using the equation ( V = IR ), you can rearrange it to ( I = \frac{V}{R} ). If the voltage ( V ) is 10.0 V, you would need the resistance ( R ) value to calculate the current ( I ). Once you have the resistance, simply divide 10.0 V by that resistance to find the current in amps.

What is inside a lightbulb?

A typical incandescent lightbulb contains a tungsten filament that emits light when an electric current passes through it. The bulb is filled with an inert gas like argon or nitrogen to prevent the filament from oxidizing. LEDs contain a semiconductor chip that emits light when an electric current passes through it.
