A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...
Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount [clarification needed] of electrical energy required by a specific consumer during a given period of time. [1] MDI instruments record the base load requirement of electrical energy .
Reference should be made to codes and standards. For example, IEC 60027, and Letter Symbols in Electrical Technology. Here are tables of widely accepted symbols. They are meant to be a guideline: Using the same symbols for the same things in different articles will increase their consistency, making them easier to understand and to improve.

Electrical resistance; Name of unit Symbol Definition Relation to SI units ohm (SI unit) Ω The resistance between two points in a conductor when one volt of electric potential difference, applied to these points, produces one ampere of current in the conductor. [32] = 1 Ω = 1 V/A = 1 kg⋅m 2 /(A 2 ⋅s 3)
