![]() To Avoid Overloading an Outletĭepending on their current rating, outlets can support different levels of electrical loads. A watts-to-amps conversion also helps avoid potential damage to your battery. So, by converting watts to amps, you can ensure faster charging rate. Then again, excessive electric current could destroy the battery. Generally, with lower amperage, charging is slower. While it is vital to match the output voltage of your solar panel to your charge controller and battery, it is also important to match amperage.Īmperage could affect the charging rate of your battery when it falls below what is expected. Using wires whose ampacity falls below the input current might cause a fire. This knowledge becomes useful when trying to ensure your wiring can withstand the incoming electric current.īy comparing the input electric current of your solar panel (or any other energy source) with the maximum ampacity of your wires, you can tell if the wires would work or if you’d have to replace them. Why Convert Watts to Amps? To Know If Your Wiring Is Good Enoughĭoing a watts-amps conversion helps give an idea of the “electron traffic” to expect in the circuit. In other words, watts is a measure of how fast electrical appliances consume or generate electrical energy. When it comes to electricity, it represents the amount of electrical energy consumed or generated by electrical devices per unit time. Essentially, amps represents the amount of electrons moving through a circuit per second. It measures electrical current, which is the rate of flow of electrical charge/electrons through a circuit per unit time. The appliance power ratings suggested are indicative only.Conversion formula: A = W / V What Is Amps?Īmps is short for amperes – the S.I unit of electrical current. Here’s our guide to the current ratings of commonly-used domestic appliances. Alternating current (AC) is used to supply things like houses and buildings and mains connected appliances. ![]() However, in alternating current (AC) the electric current changes direction at 50 times per second (50 Hz or hertz) in the UK supply.Īn example of direct current would be a battery powered torch. For direct current (DC) the electric current flows only in one direction. The labels ‘AC’ and ‘DC’ are used to describe the types of current flow in a circuit. In terms of the hosepipe example, this would refer to the amount of water being released. The higher the wattage is, the more power and output from the appliance. ![]() WattsĪmps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow. Volts are the measurement used to determine how much force is needed to cause the electric current to flow. The more water flowing through the hosepipe, the stronger the current is. You should think of electric current as the flow of water through a hosepipe. Watts / Volts = AmpsĪmps measure the flow of electricity as an electric current. Watts to Amps FormulaĪlternatively to using the calculator, here are some basic equations which allow you to calculate the missing information on your own. Find out how to convert Amps to Watts here or how to calculate Ohm's Law here.
