For example, 796 → 78% ‘on’ relative to a 100% output. Motor KV to RPM Calculation In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article on how to calculate motor KV, we can replace...
The tape and paper scenario is an electrical scenario. I am just not quite sure where the example is getting at Note that TSny asked you to calculate the magnitude of the force required to lift the calculator. He didn't specify what the source of that force was. Does the source of ...
How to Calculate Your Home’s Electrical Load Different homes need different amp services. You may be wondering, “Do I need 200 amp service?” With a bit of math, you can figure out what kind of electrical load your home requires. A 60-amp service, for example, is probably inadequate...

How can I calculate the wattage of an electrical device? To calculate the wattage of an electrical device, multiply its current (amps) by its voltage (volts). The formula is Watts (W) = Volts (V) × Amps (A). For example, if a device operates at 12V and draws 5A, its power consu...
How many solar panels will I need to power my whole home? This basically comes down to figuring out your home's total energy needs and then designing a solar array that can meet those needs. To calculatehow many solar panels your home will need:Desired energy production (kW) / Solar pane...
How to calculate the force between multiple charges? A point charge is sitting at the origin. The electric potential at x = 9.70 m is -90.0 mV. If a second charge, +2e, is put right at x = 9.70 m, what is the potential energy between the two charges?
Learn about the electric field force and how to measure electric field strength. Understand the electric field equation and how to calculate electric field. Related to this QuestionHow far apart must two point charges of 75.0 \ nC (typical of...
How to Calculate Potential Difference Typically electric potential difference will be presented in the context of an electrical circuit. In the simplest circuit, there will likely be a battery connected to a resistor with wire. The battery will have some electrical energy between the negative terminal...
You can use either of the following equations to calculate power in watts, provided all quantities are expressed in in MKS (meters, kilograms, seconds) metric units. P=F×v P=Wt If you do your measurements on the CGS (centimeters, grams, seconds) system, force is expressed in dynes and...
