Explanation

The product RC (Resistance × Capacitance) gives the time constant in an RC circuit.

Its unit is Ohm × Farad = seconds (s), which is the unit of time.

Explanation

Explanation

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)

1 kW = 1000 J/s. 

Additional Information:

The SI Unit of power is Watt.

1 Watt = 1 Joule/second.

1 Joule = 1 Newton-meter

1 Watt = 1 Newton=meter/second

Explanation

The unit of measurement for inductance is the henry (H).

It is the International System of Units (SI) unit.

The henry is named after Joseph Henry, the physicist who independently discovered inductance.

Explanation

Astronomical unit represented as (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as

149,597,870.7 in  km

(92,955,807.3  in miles).

Explanation

 The SI unit of heat is the joule (J).

Heat is a form of energy

And the joule is the standard unit for energy in the International System of Units (SI).

For instance, 1 joule of heat is the energy required to raise the temperature of 1 gram of water by 0.24°C.

Explanation

• The Candela (cd) is the SI unit of luminous intensity.
• It is defined as the luminous intensity of a monochromatic source that emits light at a frequency of 540 x 10^12 Hz with a luminous efficiency of 683 lm/W.

Explanation

Deca (symbol: da) is the SI prefix that represents a factor of 10.

It is used to denote ten times the base unit, such as 1 decameter = 10 meters.

Explanation

 Although the units for sound intensity are technically watts per meter squared, it is much more common for it to be referred to as decibels, dB.

A decibel is a ratio of the observed amplitude, or intensity level to a reference, which is 0 dB.
