Watts. A watt is a joule per second.
Watts are measured by Joules divided by seconds. The watt is the unit of power, representing the rate at which energy is transferred. It is calculated by dividing the energy (measured in Joules) by the time (measured in seconds) over which the energy is transferred.
The formula for calculating power is power = work/time, where power is measured in watts (W), work is measured in joules (J), and time is measured in seconds (s).
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
The equation for energy transferred by an electrical appliance is given by the formula: Energy (E) = Power (P) x Time (t). In this equation, Power is measured in watts (W) and Time is measured in seconds (s) or hours (h). This formula is derived from the definition of power as the rate at which energy is transferred or converted.
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.

Energy / time is known as power. In SI units, time is measured in seconds, energy in joules; the unit for joules / second has the special name watts.
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts

Power is calculated as energy consumed per unit time. If a bulb uses 3 joules of energy every 10 seconds, its power can be calculated using the formula: Power (in watts) = Energy (in joules) / Time (in seconds). Therefore, the power of the bulb is 3 joules / 10 seconds = 0.3 watts.
The power of the machine is 50 watts. Power is calculated by dividing the work done (1500 joules) by the time taken to do the work (30 seconds).
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 watts.
