However, it is not an electromagnetic law as Gauss’ law. In consequence, the Ohm’s law focuses on the property of some materials.
Circuit Breaker Selection App: This one is a fast way to determine circuit breaker sizing.That is to say, “R” is the constant and independent unit of the current “V” has a minor current fluency at a higher resistance, and “I” is directly proportional to the applied voltage and inversely proportional to its resistance. Cables Ampacity Tables: we need cable ampacity almost every day, in this app, I made it easy for you to check cable ampacity. Motor Calculator: a simple app for electrical motor calculations. Fast Electrical Calculator: the one I use for electrical calculations. Cables tables: cable most common tables, I use this one all the way. Ready to revolutionize the way you work as an engineer or electrician? Install my Android apps and discover a whole new level of productivity and efficiency.
P = I*V = 24*19 =456 Watt Don’t leave empty-handed! Install my Android Apps. DC power calculation, step-by-step exampleįor instance, we have a DC motor, its voltage is 24VDC and its current is 19A, the motor’s Power will be, P is the power, V is the operating voltage, I is the current and R is the resistance of the load. “ V LL” is line-to-line voltage Power formula for DC circuitsįor DC circuits, Power = current * voltage, or P = I * V, the resulting power is in watts. Single-phase power calculation exampleĪ single-phase motor, power rating 90 A, operating voltage 110V, 0.8 power factor, What is the motor power?
I have built an Android calculator app for you, it has all these calculations like, but not limited to:Īnd some more calculations, It’s 100% Free on Google Play Store, Install it now from here. AC power calculation step-by-step example fast electrical calculator free app While in inductive loads like single and three-phase induction motors, the voltage is ahead of the current, then a power factor is taken into account in the formula.Resistive loads have a Unity Power Factor.
In resistive electrical loads, like lighting loads and heaters, the current and voltage match, and no phase shift or angle between them, hence no power factor is needed in the power formula of resistive loads. pdf is the power factor, some times is referred to as, cos ø. V is the operating voltage of the load or the source. Power formula for AC loadsįor inductive loads, such as induction motors, the electrical power formula is given as follows: The three-phase system uses the same principle as the two-phase system but here all three parts of the current are out of phase by one-third of each.įor more information about three and single phase power read my article, Three phase vs single phase power. Similarly, we use the three-phase system to power up heavy loads like large power three-phase induction motors. While in the three phases, there are three wires, sometimes we use three wires and the neutral, 4 wires system.Ī 3-phase power is a poly-phase system that is used to transfer three times more power from electrical grids to other destinations. Single phase system contains two wires, one is neutral and the other is a phase wire. The first one is a single phase and the other three-phase system. 
There are three different types of phase systems in use. In an electrical system, the phase system is used for the distribution of load. Power generation uses 3 phase power system as the default power system around the world. Let’s dive into some examples and details! 3 phase Power
