40A*120V*5Hr = 24kW*Hr (Kilowatt-Hours)

No television would ever draw a current of 40 A!!!! Think about it, for a 120-V supply, that would make it have a power rating of 4800 W!!!!!! You would be able to use it for central heating!!!!

P=I*V

Watts = Amps x Volts

P=.40 A* 120 V

P=48watts

P=48watts*5 hours

P=240w/h or .24kWh

Current (I) = Power (P) / Volts (V)

I = P/V

I = 85 / 120

I = .708 Amperes

power=voltage*surrent

therefore power=1.5*120=180watts

if it is used for 2 hours then

power=180*2=360watt-hour or .360kwh

i = power / voltage

102 watt / 120 v = 0.85 amps

or

850 milli amps

How do you calculate Kwh saving after installing capacitor bank?

Adding a capacitor bank makes absolutely no difference whatsoever to the amount of energy consumed (in kilowatt hours). The capacitor bank might reduce the load current, but this does not affect the amount of energy consumed. Anyone who tries to sell you a 'capacitor bank' in order to save you energy is selling a SCAM!


A flat iron that has a resistance of 10 ohms is used for about 4 hourshow much heat is produced if the current is 10 amperes?

This can be calculate quite simply using the following steps. First calculate the power loss (as heat energy) from the iron using the relationship: P= I2R, P is power in Watts, I is current in Amps, R is resistance in Ohms. In this case P = 102 x 10 = 1000 W Next convert 4 hours into the standard time unit, seconds. 4 hours = 60 seconds per minute * 60 minutes per hour * 4 hours = 14400s Finally calculate how much heat energy is produced during this time using the relationship: E = Pt, P is power in Watts, E is energy in Joules, t is time in seconds. In this case E = 1000 x 14400 = 14400000 J Or more appropriately 14.4 MJ (megajoules). Hope this helps, Tom


Why do people recycle aluminum instead of mining for more?

Aluminum is the only material that's endlessly recyclable, and It takes energy to make aluminum from scratch. In fact, it takes 95% more energy to make aluminum from bauxite ore than to recycle old aluminum into new. The energy you save by recycling a single aluminum can will run a TV for three hours.


How do you calculate current consumption per hour?

You are confusing energy and current. You consume, and pay for, energy -not current.For the purpose of billing its customers, an electricity utility measures energy in units called kilowatt hours. In the UK, a kilowatt hour is also called a 'unit', short for 'Board of Trade unit'. The Board of Trade, which no longer exists, used to be the government organisation responsible for setting energy prices.A unit, or kilowatt hour, of energy is the amount of energy consumed at the rate of one kilowatt over a period of one hour. So, to determine the number of units that an electrical load 'consumes', you simply multiply its power in kilowatts by the time for which it operates, in hours.


Why is the electric watt meter connected in series with the rest of the circuits in the house?

First of all, you are referring to an energy meter, not a wattmeter. A wattmeter measures power, in watts, whereas an energy meter reads energy, in watt hours (or, more specifically, kilowatt hours). The energy company bills you for energy, not power.Having said that, the connections each instrument are the same. In fact, there are two coils inside an energy meter: a current coil, and a voltage (or potential) coil. The current coil is connected in series with the load while the voltage coil is connected in parallel with the supply voltage.The current coil measures the in-phase component of the current drawn by your load, so that the instrument always reads the true power (multiplied by time -the function of the aluminium disc) of the load -i.e. not the apparent power or reactive power.

Which appliance will use the most energy if it is run for 15 minutes?

Two formulas are needed to calculate the answer:[Energy (watt-hours)] = [Power usage rate (watts)]? x [Time (hours)]and[Power usage rate (watts)] = [Voltage (volts)] x [Current (amps)]?


How many hours could you run a TV on the energy you save by recycling just one can?

You can run a TV for three hours on the energy saved by recycling one aluminium can.


How many hours have for a 4400 mAh?

This is an informal unit for energy, often used for batteries. mAh = milliampere x hours. If you know how much current you will need (in milliamperes), you can divide the 4400 mAh by the amount of current, to calculate how many hours the battery will last.


How do you calculate the percentage of 40 hours?

Percentage of what during 40 hours? During a 40 hour period you watch TV for 15 hours. 15 / 40 x 100 = 37.5% of time watching TV


Does a PS3 waste a lot of energy?

I have a ps2 and i use it for about 3 hours, for a ps3 it use the same amount of energy for about 2 hours (thats like having an old tv on for 2 hours) so i guess you should play it for about 2 hours and it will not use too much energy! The PS2 uses 8.3 volts DC and far less power than a PS3 but both connect to TV sets. The question of whether playing a PS3 is a waste of energy could be applied to the TV just as easily.

How can solar energy be used to run a television?

solar panels run energy to a controller then to a enough batteries to provide the needed amp hours to run a tv. From the battery you need to have a inverter to turn 12volt to 110volt. The tv runs of this line. First calculate watts per hour the TV use's,then how much time the TV is used ,convert this to amps per hour of use to see how many batteries you will need. Also you have to calculate the amount of solar power . How much sunlight and temp outside also how many panels to supply your needs. PS dont forget the main line should be fused with the correct size fuse

How much electricity does it cost to run a 32 inch sharp tv for 10 hours?

I am estimating the tv draws a power of 150 Watts, so that in 10 hours it uses 150x10 Watt-hours, which is 1.5 kilowatt-hours, also known as 1.5 units, of electrical energy. The price is probably about 20c per unit so the answer is 30 cents.


How do you calculate a housholds electricity use?

You will not be able to substantiate how much electrical energy you've used; that's why there's a meter to measure your usage. Here are a few reasons: a. You will have to determine how much energy is used by each and every appliance, lamp, charger, radio, television, PC, monitor, etc. b. You will have to record every light left on when you're out of the home, every clock that is left running, that outdoor light you forgot and all the digital clocks. c. Don't forget energy leakages. d. Then you'll have to convert minutes of usage in terms of hours. e. The formula for your question is: (Energy in kilowatt-hours) E = (power in kilowatts) P X (time in hours) t .
