Derivations in alternating current class 12
WebAn alternating current can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC which always flows in a single direction as shown below. WebThe average power of an alternating current circuit can be calculated by calculating the instantaneous power of the circuit. In an AC circuit, the average power dissipation can be …

The R.M.S. value refers to the effective or virtual value of alternating voltage. The RMS value is also denoted through these symbols Vrms, Veff, or Vv. The formula of RMS value of AC is: I rms = I0 √2 = 0.707I 0 I r m s = I 0 2 = 0.707 I 0.
WebCurrent electricity is generated by power plants and batteries. Static electricity is generated when objects are rubbed against each other resulting in charge transfer. Current electricity is controlled. Static electricity is uncontrolled. The electricity that is used to power up electronic devices is an example of current electricity.
