The rotor is a series of large electromagnets that spins inside a tightly-wound coil of copper wire, called the stator. The magnetic field between the coil and the magnets creates an electric current. In the Hoover Dam, a current of 16,500 amps moves from the generator to the transformer,...
The reason is simple: your electric bill is measured in kWh, and you get charged based on the kWh of electricity you use per month! How many volts and amps does a washing machine use? The wattage of an appliance is determined from its voltage and amperage. You can use the yellow ...
Question: How many amperes flow through a 60-watt bulb when 120 volts are impressed across it? Power: The total power generated in a complete circuit is equal to the product of voltage and the amount of current flowing in the circuit. Based on Ohm's law, the volt...

100Ah 12V Battery Capacity = 100Ah × 12V = 1,200Wh Now, this 1,200Wh battery capacity is the most useful piece of information when it comes to determining how long will a 100Ah battery last. It has 1.2 kWh of juice; for comparison, Tesla S model has a 100 kWh battery. Here are...
Every EV user has wondered about this. There's no simple answer, but knowing the variables will help you better estimate the time it takes for an EV fill-up.
When you plug your Tesla into a DC fast charger, it takes a minute to communicate the proper charging speeds. Then you might be able to achieve maximum speeds when the battery’s state of charge (SoC) is between 10-30%, after which your Tesla will charge much slower. ...
The battery is charged by plugging it into the mains electricity. All that’s needed to do this is a charge point or plug socket, and a compatible cable running from the charge point to the vehicle. There are three places you can charge an electric car: at home, at work, or at a...
Phone chargers usually use one to two amps and connect to a 120-volt outlet. How many times you charge your phone has a large impact on how much electricity your phone charger uses. Assuming one full charge takes one hour: Charging your phone once per day uses 0.035 kilowatt-hours (kWh...
This is defined as power output per kg of mass (per kg of the energy storage medium. for example: per kg of batteries). It can be calculated by dividing power output by weight. Power density is measured in W/kg (watts per kg). It is how many watts of power a 1kg battery can pro...
