To understand the difference between an amp and a joule, you need to understand voltage. Voltage is the difference between the number of electrons in one place and the number in another. Imagine that you have not yet turned on the hose full of molasses. There is a lot of molasses waiting...
Understanding the relationship between amps and other electrical units is essential to grasp the full picture of electrical systems. Let's explore the relationships between amps, volts, ohms, and watts: Amps and Volts:Volts (V) represent the unit of electrical potential difference or voltage. Curre...
Elmo's Fire is a dramatic difference in charge between the air and a charged object, like the mast of a ship, the tip of an airplane wing or the 30-foot steeple of a church -- things we often think of as potential lightning rods. When the voltage gets high enough, usually around ...
Once you have those specs, the formula is:Voltage (V) × Current (I) = kVa1000 For example3-Phase Power System The basic formula for calculating the kilovolt-amps of a 3-phase power system uses the same specs as for a single-phase system divided by the square root of three....
2. What is voltage? The potential for energy to travel is represented by voltage (V), which is equivalent to water pressure. Voltage has characteristics similar to water flowing through pipes. The "water-flow analogy," which compares electric circuits to a closed system of water-filled pipes,...
terminal, the non-inverting input terminal (+) and the inverting input terminal (-) are considered to have the same voltage applied, that is to say, it can be considered as a virtual short circuit. Therefore, when the positive input terminal (+) is 0V, the voltage at point A is also...
Amps and Volts Electricity is to home electrical circuits as water is to home plumbing systems. The voltage is roughly equivalent to the water pressure, and the amperage, or current, to the quantity of water that flows past a given point per second. At a given pressure, less water can get...
How many watts is a Macbook Pro charger? If the charger's wattage isn't explicitly mentioned, you can utilize the following formula to calculate it: Watts = Volts x Amps By knowing the voltage and current ratings (in amps) of the charger, you can easily determine the Macbook Pro charg...
How to size your charge controller (mppt vs pwm) Overall, charge controller sizing is not as difficult as you may think. Charge controllers are rated and sized depending on your solar array's current and the solar system’s voltage. You typically want to make sure you have a charge control...
Nucleus-M motors need a minimum of about 10 volts and uses 2 amps. That means it is about 20 watts. We suggest to keep it at around 12 volts especially if using more than one motor. A voltage readout can now be seen through the new firmware. It is located on the top left of eac...
