What is Ohm's Law?

Ohm's Law defines the relationship between voltage, current, and resistance. It was discovered by German physicist Georg Ohm and it was published in 1827.

According to Ohm's law if the resistance of an electrical circuit is increased, and voltage remains same, then the current will increase.

If the voltage across resistance is doubled, then the current will double as well.

The symbol of ohm is Ω.

What is Ohm's Law Formula?

V=IR where V is voltage (volts), I is current (amperes), and R is resistance (ohms).
