An Electrician in Pasadena Explains Ohm’s Law

There are many “laws” or rules when it comes to electricity. While most people will still need to call an electrician Pasadena for major electrical problems, it is still nice to understand the basics so you know what is happening with your electrical devices when you plug them in or flip the switch to the on position. One of these so-called laws is “Ohm’s Law.” Learn more about how it works with your appliances.

First, you must understand that for electricity to work, it must complete a circuit (loop). Generally, these circuits are controlled by copper wire because it has a very low resistance and carries the current with ease. The amount of current flow is decided by the amount of resistance in the circuit. If the resistance is high, then the current will be low. For the current to be high, the resistance must be low (such as it is with copper wire.) This is the basis for Ohm’s Law.

While it may seem like having a higher current would be better, this is not always true. Too much current can be dangerous. For household circuits, it is normally best to keep the current under 20 amperes. More than that will pop the circuit breaker. When your circuit breaker pops, that is keeping you and your family safe from having too much current flow through the devices in your home.

Ohm’s Law may not be something that you need to understand in depth, but having this basic knowledge will make it easier to know what is going on behind the scenes of your electronics.
