How can we increase the speed of motor give two ways? The speed of rotation of an electric motor can be increased by: (i) increasing the strength of the current, (ii) increasing the number of turns in the coil. What is DC motor speed? Speed of a DC Motor A = number of parallel paths. […]
Why are periodic forest fires beneficial to the forest?
Why are periodic forest fires beneficial to the forest? When done in small doses, controlled burns can be beneficial to forest growth. Naturally, periodic forest fires help to clear away old brush and allow for new growth. They recycle nutrients back into the soil, disperse seeds of fire-adapted plants and burn ground cover to give […]
Are hydrogen or electric cars better?
Are hydrogen or electric cars better? Hydrogen fuel cell vehicles tend to be more frugal than their battery electric counterparts. According to Autocar, the Hyundai Nexo comes with a real-world range of 414 miles and filling up takes just five minutes, whereas electric charging can be an hour-long affair at the best of times.

How many amps does starter motor draw?
How many amps does starter motor draw? 150 amps Why do motors draw more current when starting? An induction motor during start behaves like a short circuited transformer. Now, when supply is given to the stator windings, it draws high current at constant voltage as the windings are short circuited. This high current through the […]

How do you measure wind speed without an anemometer?
How do you measure wind speed without an anemometer? A much simpler way to measure wind speed is with a ribbon tied to a stick. Once calibrated, the device will allow the casual kite-flyer or sailor an indication of the wind speed. Place the three ribbons on top of each other and tie them together […]
Why did Germany not invade Sweden?
Why did Germany not invade Sweden? Hitler did not invade Sweden because he did not want to waste valuable troops in Scandinavia when he had other concerns.
