Electrical power is expressed in watts or?
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
Is TV volume measured in dB?
All sound output can and is measured in dB (decibel's)
What are the critical and non critical measurement in power system?
In a power system, critical measurements include voltage levels, current levels, frequency, and power flow. These are essential for monitoring system stability and ensuring proper operation. Non-critical measurements may include temperature, humidity, and light levels, which can provide additional information but are not essential for system operation.
What is power measured in?
Power is measured in watts.
How to calculate the energy used in a system?
To calculate the energy used in a system, you can use the formula: Energy Power x Time. Power is the rate at which energy is used or produced, measured in watts (W), and time is the duration for which the power is used, measured in seconds (s) or hours (h). Multiply the power by the time to find the total energy used in the system.
Is it true that power is the rate at which work is done and is generally measured in horsepower?
Yes, power is the rate at which work is done. It is generally measured in watts in the International System of Units (SI) but can also be measured in horsepower. Horsepower is a unit of power that is often used in the context of engines and machines.
Why power is measure in db?
Power is often measured in decibels (dB) because it allows for a relative comparison of power levels. dB provides a logarithmic scale that makes it easier to compare a wide range of power values. It is particularly useful for measuring power changes in systems where there is a large variance in power levels.
What is the Difference between active and apparent power?
Active power is the real power consumed by an electrical device to perform work, measured in watts (W). Apparent power is the combination of active power and reactive power, measured in volt-amperes (VA). Apparent power represents the total power that is supplied to the system, while active power represents the actual power consumed by the system.
Power is measured in j per what?
Power is measured in Joules per Kilowatt.
What includes levels of hierarchy?
A hierarchy includes different levels of authority or importance within an organization or system. Each level has its own set of responsibilities and decision-making power, with higher levels typically having more authority than lower levels. Hierarchy helps to establish clarity in reporting relationships and promote efficient communication and decision-making.
The metric system is measured in what?
It depends on what you are measuring! Distance is measured in metres Time is measured in seconds Mass is measured in kilogrammes Volume is measured in litres Force is measured in newtons Energy is measured in joules Temperature is measured in kelvin Power is measured in watts Electromotive force is measured in volts Electric current is measured in amperes ...and so on
Which social system in which different races have different levels of power?
Racial hierarchy
