Power = V x A = 6 x 0.5 = 3 watts = 3 joules per second
dissipated by the lamp into the surrounding environment
in the form of heat and light.
100 joules/second = 100 watts.
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.
That is called power. In SI units, it is measured in Joules / second, which is called Watts.
That is called "power". The SI unit for power is the watt, which is equal to joules/second.
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
Power is energy / time. In SI units, joules / second, also known as watts.
100 joules/second = 100 watts.
100 joules/second = 100 watts.
100 joules/second = 100 watts.
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
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.

"kilowatts" is a rate, not a time. A kilowatt is 1000 watts, or energy being transferred at 1000 joules per second. (A watt is a joule per second.) Your question means the same as this question: "What is the measurement in time for 100 forty-watt lightbulbs?" You can leave the lights on as long as you wish. Collectively, every second they will convert 4000 joules of electrical energy to light and heat energy.
That is called power. In SI units, it is measured in Joules / second, which is called Watts.
