Voltage is a measurement used in defining the strength or difference in charge for an electrical current. It is a means of measuring the current and showing the difference between different types of energy and different points. It is the potential of electricity between two points and the difference of their energy. These differences are expressed in voltage on different types of electrical outlets such as batteries. Voltage is also used in homes for the electricity and it is important that the voltage is correct for the home and the uses.
It is important that if you have an electrical change in your home or building or you are buying a home, you will want an electrical inspection to make sure that the voltage is correct throughout. The home inspector will use a voltage meter to make sure that the current coming into your home and going out of your electrical outlets is steady and correct. The wrong voltage can cause fires and other hazards within your home that are dangerous and costly. A professional can also tell you if the building has the correct electrical voltage to handle specific household appliances such as a clothes dryer, refrigerator or stove.
