WebRMS or root mean square current/voltage of the alternating current/voltage represents the d.c. current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2. Created by Mahesh Shenoy. Sort by: WebKirchhoff's Current Law. Kirchhoff's Current Law says that the sum of all currents flowing into a node equals the sum of currents flowing out of the node. It can be written as, \large \displaystyle \sum i_ {in} = \sum i_ {out} ∑iin = ∑iout. crfic
