What is the power of an electrical cable car that uses 3500 joules every second?
3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.
What unit is power measured in?
The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.
What is the unit for measuring electrical power?
Electrical power is measured in watts.AnswerPower is measured in watts. There is no such thing as 'electrical power' as power is simply a rate.voltThe basic unit of electrical power is the watt. If the power is very large, then kilowatts (thousands of watts) or megawatts (millions of watts) are also used.Power is simply a rate, so you cannot really have 'electrical' power, 'mechanical' power, etc. In the SI system of measurements, power is measured in watts (W).Electric power is usually measured in watts, kilowatts, or sometimes megawatts. One watt is equal to one volt-ampere or one joule per second.Electric power is the rate at which an electrical circuit transfers electric energy. The SI unit of power is the watt which is one joule per second.Wattage, Watts, and (W) are what power is measured in there just different ways to say watts."Watts" is the term used to define a quantity of power. If you were looking for a device used to measure power, that is called a wattmeter.Technically, power is a measure of how fast energy is consumed, so energy can be measured as power multiplied by time.AnswerThere is no such thing as 'electrical' power, as power is simply a 'rate'. Power is a measure of the rate of doing work, transferring energy, or of heat transfer. As energy, work, and heat are all measured in joules, power is measured in joules per second which, in SI, is given a special name: the watt.Another example of a 'rate' is velocity. We do not describe different times of velocity; neither should we describe different types of power.Electrical power in SI is measured in watts, or joules per second. It is equal to current times voltage, which is also equal to current squared times resistance. (P=IV and V=IR, where P is power, I is current, V is voltage, and R is resistance.)The watt is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt. The unit, defined as one joule per second, measures the rate of energy conversion.
What unit is the electrical power of light bulbs measured in?
I dont know i sorry some idiot changed the answer it was a awfull answer so please dont get up set about not finding ur answer....
How is power measured?
In physics, power is the rate at which energy is transferred, used, or transformed. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine). For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts-the more wattage, the more power, or equivalently the more electrical energy is used per unit time.
What starting with w is a unit electrical power?
The watt, which is equal to 1 joule/second.
What starting with w is a unit of electrical power?
The watt, which is equal to 1 joule/second.
In what metric unit is power measured?
The basic metric unit for electrical power measurement is the watt, which is equal to one joule per second.
State the units of measurement for mechanical energy and electrical power?
The official unit for any type of energy (not just mechanical energy) is the joule. The official unit for any power (not just electrical power) is the watt, equal to joules / second.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
The power of the light bulb is 100 watts since 1 watt is equal to 1 joule per second.
How many watts equals 1 joule?
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
The rate at which energy is transfered is called?
That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.That is called "power". The SI unit of energy is the joule, the SI unit for power is the watt, which is equal to joules/second.
1 watt of power equals how many joules?
1 watt is equal to 1 joule per second. This means that 1 watt of power equals 1 joule of energy expended over a period of 1 second.
What are the differences between a joule and a watt?
Joules versus wattsThe joule and the watt are closely related units. The joule is a unit of work and energy. It is equal to a newton-meter (N-m). Note that the unit of torque is also the newton-meter, but scientists don't use the word joule when they are talking about torque.The watt is a unit of power and is defined as a joule per second, so you can see that power is work per unit time.One joule is equal to one watt-second.
What is power and what is the unit for power?
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.
What is the unit of measurement used to express the energy emitted per second?
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
Is a watt a unit of power or a unit of electrical energy?
Watt is a unit of power. 1 Watt = 1 Joule/second; joule is the unit for energy.
