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.

What else can I help you with?
How much energy does a 5 watt light bulb produce?
None. But it does convert 5 watts of electrical power (energy per unit time) into 5 watts of [light + thermal] power.
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
What does electrical energy equal?
Electrical energy is the ability of an electrical system to do work. It is measured in joules and is equal to the product of power (in watts) and time (in seconds). In mathematical terms, electrical energy equals power multiplied by time.
How long could 90 Js of energy light a 40 Watt light balb.?
To calculate this, we first need to convert the energy from joules to watt-hours. 90 joules is equal to 0.025 watt-hours. Therefore, with 0.025 watt-hours of energy, a 40 watt light bulb would last for approximately 0.000625 hours or 0.0375 minutes.
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).
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?
100 joules/second = 100 watts.
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 much energy does a 5 watt light bulb produce?
None. But it does convert 5 watts of electrical power (energy per unit time) into 5 watts of [light + thermal] power.
What is the conversion from joules of energy to watts of energy?
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
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.
What does electrical energy equal?
Electrical energy is the ability of an electrical system to do work. It is measured in joules and is equal to the product of power (in watts) and time (in seconds). In mathematical terms, electrical energy equals power multiplied by time.
How many joules equals 1 kilo amp?
This is not a valid question by itself. Joules are units of energy, while Amps are units of electrical current. However, if you also know the Voltage of the electrical current, you can multiply the Current[Amps]*Voltage[Volts] to get the Power in Watts. Watts are equivalent to Joules per second. If you then know the amount of time of the current flow, you can calculate the total number of Joules by multiplying the Power[Watts]*Time[seconds] = Energy[Joules] .
Why are electrical devices represented in watts?
A Watts is a measurement of power or energy usage represented by W. When you see this on an electrical device, say a sticker on an appliance, it tells you how much energy it will use in watts, or Joules per hour. This allows the consumer to compare similar appliances based on energy usage.
