A typical 13 inch MacBook Pro consumes 61 Watt power as you can see in the charger provided while a 15 inch MacBook consumes 87 Watt per hour, MacBook users know that. Based on the data above, we can easily calculate the cost of electricity that your Apple MacBooks can consume each ...
Step A: Convert watts to amps Actually, watts is the fundamental unit of power and watt-hours is the energy stored. The key is to use thewatts you know to calculate the amps at the battery voltage. For example, say you want to run a 250 watt 110VAC light bulb from an inverter for...
The power requirement of a house depends on the type and number of appliances that family members use. On average, 40-63 amps is mostly sufficient for houses. Many electrical service providers offer an electrical load calculation formula pdf to help you calculate and understand your load. ...

The basic idea of portable power is nothing new; people have always had ways of making energy on the move. Evenprehistoric humans knew how to burn woodto make fire, which is another way of producing energy (heat) from chemicals (burning releases energy using achemicalreaction called combustion...
Here's How to Calculate It Yourself Measure the Charger with a Watt Meter Summary Smartphones are very energy efficient. It costs less than one dollar to completely charge a smartphone battery every day for a whole year. This is true for iPhones, Samsung Galaxy phones, and other Android phon...
On road and street courses, the brakes use special cooling ducts to bring more air over the rotors. The engine needs air to breath. An air intake at the rear of the car provides a stream of air directly to the turbocharger. The screen keeps debris out of the air intake -- debris ...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
Off-grid solar is a great way to be energy efficient, but it needs proper planning. Learn how to size your solar array with our expert tips.
To calculate the amount of power a turbine can actually generate from the wind, you need to know the wind speed at the turbine site and the turbine power rating. Most large turbines produce their maximum power at wind speeds around 15 meters per second (33 mph). Considering steady wind spe...
