There are different units for electricity, depending on what you want to measure; for example: volts to measure voltage amperes to measure current watts to measure power etc.
There are lots of different units for electricity, depending what aspect you want to measure (power, energy, current, voltage, frequency, etc.).For a power plant, some relevant units include: * Volt, for voltage * Ampere, for current * Watt, for power * Hertz, for frequency
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
Wattage refers to power power is voltage times current. P = V*I Therefore, in order to know the voltage you need you also need to measure the current (units of amps).
The unit of measure for current load is amperage, or simply amps.
The standard unit used to measure sound power is the decibel (dB).
The different optical power units used to measure the intensity of light in optical systems are diopters and watts. Diopters measure the refractive power of a lens, while watts measure the total power of light emitted or transmitted through a system.
Cubic units are used to measure 3-Dimensional objects. The cubic(x to the third power) units are used to demonstrate the 3 dimensions.
Power = Voltage x Current Watts = volts x Amps
A multimeter is a common instrument used to measure electrical current. It can measure current, voltage, and resistance in electrical circuits.
Here are some common units, and what they measure:volt - voltage ampere - current ohm - resistance siemens - conductance hertz - frequency (dimensionless number) - power factor watt - power
some SI units: length = metres time = seconds mass = kilograms electric current = amperes temperature = kelvin
