Is the length of time an electrical load is on proportional to power or energy?
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.
Will the value of joules constant be same if AC were used instead of DC?
Joules measure energy (power x time). If the AC voltage is expressed as rms (root mean square) and not peak, and there are no capacitors or inductors in the circuit, then the joules per second (=power ) will be the same.
How do you convert Volt Ampere into Joules?
You can't. If you know the voltage (volts) and current (amperes), you can convert to power (watts), but power is not energy. Power is the rate of energy (joules per second). You need to know the time as well to determine energy.

How much electrical energy does a 100W lamp use in 1 second?
Watts measure power. Energy is measured in joules and is the product of power and time. 1 joule = 1 watt for 1 sec Energy used in the example = 100 x 1 = 100 joules
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
Find the work you do when you exert a force of 40 N to run a distance of 18 m in 4 seconds?
The work is Work= FD= 40x18= 720 Joules. The power is W/seconds = 720/4= 180 Watts.
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
What is the power output of an engine that does 60 000 joules of work in 10 seconds?
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
If a worker used 6000 joules of work to pull his sled 70 seconds what power does he need?
6000 joules / 70 seconds = 85.71 watts
How do you calculate power if don't know joules?
Well, the first step is to learn joules and you'll be set!
How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
How much power does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
How much power is used when 600J of work are done in 10s?
60 W
What is the power of 50 joules in 5 seconds?
Power = energy/time = 50/5 = 10 watts
