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.

The power output of the lamp can be calculated using the formula P = V * I, where P is power (in watts), V is voltage (in volts), and I is current (in amperes). For the lamp with 6V and 0.5A, the power output would be 3 watts. One watt is equal to 1 joule per second, so the lamp is transferring 3 joules of electrical energy per second.

What is expressed as joules per second?
Power is expressed as joules per second. It is a measure of the rate at which energy is transferred or converted.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
In 2 seconds, a 100 Watt light bulb consumes 200 Joules of electrical energy from the electrical supply (100 Watts * 2 seconds = 200 Joules).
What does power 200 joules mean?
Power represents the rate at which work is done or energy is converted. In this case, a power of 200 joules means that 200 joules of energy is being transferred or converted every second.
The rate at which an electrical device converts energy from one form to another?
This is called the power of the electrical device. Power is the rate at which energy is transferred or converted. It is typically measured in watts (W).
What is a rate at which energy is converted?
Power is the rate at which energy is converted or transferred. It is typically measured in units such as watts (W) or joules per second (J/s).
How are electrical power and electrical energy related?
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
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?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
What is expressed as joules per second?
Power is expressed as joules per second. It is a measure of the rate at which energy is transferred or converted.
What is power at which energy is transferred?
Power is energy / time. In SI units, joules / second, also known as watts.
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.
What is the energy used in one second when a bulb have 40Watts.?
The energy used by a 40W bulb in one second is 40 Joules. This is because power is defined as the rate at which energy is transferred or converted, so if the bulb consumes 40W of power in one second, it uses 40 Joules of energy in that time period.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
In 2 seconds, a 100 Watt light bulb consumes 200 Joules of electrical energy from the electrical supply (100 Watts * 2 seconds = 200 Joules).
The rate at which an electrical device converts energy from one form to another?
This is called the power of the electrical device. Power is the rate at which energy is transferred or converted. It is typically measured in watts (W).
What does power 200 joules mean?
Power represents the rate at which work is done or energy is converted. In this case, a power of 200 joules means that 200 joules of energy is being transferred or converted every second.
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.
