A dc machine is a device which converts mechanical energy into electrical energy into mechanical energy or vice versa. When the device or machine acts as a generator mechanical energy is converted into electrical...

Series or Voltage Resonance: Consider an ac circuit containing resistance of R ohms, inductance of L henrys and capacitance of C farads connected in series, as shown in fig.3.21 (a). Impedance of the circuit...

In delta to star transformation “ the resistance of any arm of star is equal to the product of the resistance of the two delta side meeting it divided by the sum of three...

As we know that the electric current is the rate of flow of electric charge (electrons). It is denoted by I and its unit is Ampere (A) and a complete path which consist one...

For a given a system of linear equations, Cramer’s Rule is a handy way to solve for just one of the variables without having to solve the whole system of equations. They don’t usually...

In this method, one node of the circuit is taken as lowest potential reference at zero volts (called circuit ground); while the voltage of other nodes are assumed to be V1,V2,V3. with respect to...

In simple case, we can calculate the equivalent resistance as well as voltage and current in the circuit using Ohm’s law. But in more complex circuit or network the calculation is done with the...
