The correct answer is: Power level.
A decibel (dB) is a logarithmic unit that expresses the ratio of two values of a physical quantity, often power or intensity, in a way that conveys the ratio’s order of magnitude.
The decibel is not a unit of power or intensity itself, but rather a way of expressing the ratio of two values of power or intensity. For example, a sound that is 10 decibels louder than another sound has a power that is 10 times greater.
The decibel is often used to measure sound intensity, but it can also be used to measure other quantities, such as electrical power, light intensity, and seismic activity.
- Current is the flow of electric charge through a conductor. It is measured in amperes (A).
- Voltage is the difference in electric potential between two points in a circuit. It is measured in volts (V).
- Power is the rate at which energy is transferred or converted. It is measured in watts (W).
The decibel is not a unit of current, voltage, or power. It is a unit that expresses the ratio of two values of a physical quantity, often power or intensity, in a way that conveys the ratio’s order of magnitude.
