How Do You Solve average power?
If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage.
An ac voltmeter attached across the terminals of a 45-Hz ac generator reads 7.07 V..
How much power is required to move a car?
Outcome: In even terrain the car consumes more than 3kW to maintain 40km/h. Accounting that the weight is 1200kg and power to overcome friction is four times that of a 300kg vehicle, about 1.2kW are needed simply to overcome friction. This also means, about 2kW are needed to overcome air drag.
How many kilowatts does it take to power a car?
A standard EV battery requires 30 kWh per 100 miles. 1 Using the average national residential utility rate of about 13 cents per kWh, we can find how much it costs to drive those 100 miles.
How is car power calculated?
You will be using the formula (RPM * T) / 5252=HP, where RPM is the engine speed, T is the torque, and 5,252 is radians per second. The first calculation you want to do is multiply the torque and the engine speed.
Do electric cars lose charge when parked?
In light of the explanation I gave above, the simple answer is that most likely yes, your EV is losing some amount of charge while parked and idle. If you’re still plugging your car in each day and maintaining the charge level between 20 and 80 percent, then the amount you’ll lose to vampire drain will be minimal.
How many watts does it take to lift 1kg?
10 WattsIf you can keep lifting a 1 kg weight to a height of 1 meter every second, weight after weight after weight, then you will be steadily producing 10 Watts of power.
Does a moving car have potential energy?
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). … A moving car possesses mechanical energy due to its motion (kinetic energy).
How far can you drive on 1 kWh?
3 to 4 milesOn average, most electric cars can travel 3 to 4 miles on 1 kWh of electricity.
What is the efficiency formula?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is work formula?
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.
What is the formula of power in electricity?
Electrical Energy in Circuits In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can also be defined as the rate of by which energy is transferred.
How much does an electric car make your electric bill go up?
That figure will tell you the cost per 100 miles. You also can work from the total kilowatt-hours it takes to recharge the EV’s battery. If an EV requires 40 kWh to recharge a fully depleted battery, and the rate is 18 cents per kWh, that’s $7.20 for a fill-up.
How do I calculate power?
Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
Is charging an electric car cheaper than gas?
Over the anticipated 15-year life span of a vehicle, the electricity required to run a battery-powered electric car can be as much as $14,480 cheaper than fueling up an internal combustion vehicle. … Then there are electricity costs, which make the notoriously unstable costs of gasoline look simple by comparison.
How many units is 1kw?
If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.
What is the formula of Joule?
Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. On substituting equation (2) and (3) in equation (1) we get, Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2].
How many kWh does a Tesla use per mile?
All come with a 100 kWh battery. If you have the Long Range variant – which has an impressive range of 412 miles – it costs $15.29 for a full charge based on electricity prices of $0.13 per kWh and 85% charging efficiency. That gives you a charge cost of $0.037 per mile, or $3.70 per 100 miles.
What is average power formula?
Use rms voltage and/or rms current to calculate average power, resulting in meaningful power values. The peak-to-peak amplitude of a sinusoid is the rms value multiplied by 2√2. For a sinusoidal voltage, V p-p = V rms × 2√2, where V p-p is the peak-to-peak voltage and V rms is the rms voltage.
How many joules does it take to move a car?
. For a car going 55 mph for 3600 s, the work is approximately 3 10 8 J . That’s quite a bit of energy!
What is the longest distance an electric car can go?
At more than 400 miles, the Model S Long Range Plus offers about double the maximum distance you can cover in the Porsche Taycan or Audi e-tron. By the end of the year, Tesla will release the 2021 Model S Plaid+, which boasts an estimated range of more than 500 miles, according to Tesla.
What horsepower is 5252?
One horsepower is equal to 33,000 foot-pounds of work per minute. Add in the equations relating to torque and velocity, and you’ll find that horsepower always equals torque multiplied by rpm, divided by 5,252. Canceling out the equal variables, you wind up with horsepower equaling torque… at 5,252 rpm.
