Ohm's Law is a simple way to understand how voltage, current, and resistance work together in electrical circuits.
It can be summed up with a simple formula:
V = I × R.
This means:
Voltage (V): This is like the push that drives the electric current through a circuit.
Current (I): This is the flow of electric charge. We measure it in amperes (A). Think of current as how much electricity is moving through a point in the circuit at any time.
Resistance (R): Measured in ohms (Ω), resistance tells us how much a part of the circuit slows down the current.
With Ohm's Law, if you know any two of these parts, you can easily figure out the third one. For example, if you have the voltage and the resistance, you can find the current using this formula:
I = V ÷ R.
Ohm’s Law is really useful in real life. It helps engineers design electrical devices and also helps people fix problems in circuits.
When there are many resistors connected in a circuit, Ohm's Law teaches us how to find the total resistance, using rules for series and parallel setups.
In short, Ohm's Law is a handy tool that makes it easier to understand how electricity works. It turns a complicated topic into something simpler, helping us learn more about electrical systems.
