*Learn key terms and descriptions Physics - Alternating Current*
*Term* : Effective Value or rms Value of AC
*Description* : It is defined as the value of AC over a complete cycle which would generate same amount of heat in a given resistors that is generated by steady current in the same resistor and in the same time during a complete cycle. The 70.7% of peak value of current gives effective or rms value of AC.
*Term* : Wattless Current
*Description* : The current in an AC circuit when average power consumption in AC circuit is zero, is referred as wattless current or idle current.
