The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?
1 joule is the energy equal to 1 watt for 1 second.
100 joules = 100w for 1 second.
A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.
Only about 1% of this is useful light, the rest is wasted as heat.
Answer
Power is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).
So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.

How much heat energy is produced from 3000 joules of electrical energy?
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
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 at which an electrical device converts energy from one form to another?
The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.
What do you call to the rate at which an appliance converts electrical energy into other forms of energy?
The rate of conversion of any type of energy is called power. In the international system (SI), the unit for energy is the joule; the unit for power is the watt, which is 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.
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?

What is a measurment of electrical energy?
Electrical energy is measured in the same units as any other type of energy: joules.
What is used to measure of electrical energy?
All energy is measured in joules.

What is the between work and power?
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.
How many joules of light energy are in 1440 watts of electrical energy?
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.

The power of the light bulb is 100 watts since 1 watt is equal to 1 joule per second.
What can be measured in joules?
Various forms of energy can be measured in joules, such as kinetic energy, potential energy, heat energy, and electrical energy. Joules are a unit of measurement for energy and can be used to quantify the amount of energy present in a system or the amount of work done.
