Power Dissipated in Resistor. Convenient expressions for the power dissipated in a resistor can be obtained by the use of Ohm's Law.. These relationships are valid for AC applications also if the voltages and currents are rms or effective values. The resistor is a special case, and the AC power expression for the general case includes another term called the power factor which accounts for. A circuit element dissipates or produces power according to where I is the current through the element and V is the voltage across it. Since the current and the voltage both depend on time in an ac circuit, the instantaneous power is also time dependent. A plot of p(t) for various circuit elements is shown in .For a resistor, i(t) and v(t) are in phase and therefore always have the same sign.

Calculate the value of the power factor of the circuit in each case. [All India 2008C] Ans. 3 Marks Questions. 16. A voltage V = V 0 sin wt is applied to a series L-C-R Derive the expression for the average power dissipated over a cycle Once you have that, you can use Ohm's law to find the voltage drop across the resistor. Then you should be able to find the voltage at the node. You can then find the voltage across the current sources and use power equations to solve it

• A voltage V = V 0 sin ω t is applied to a series LCR circuit. Derive the expression for the average power dissipate over a cycle. Under what conditions is (i) no power dissipated even though the current flows through the circuit, (ii) maximum power dissipated in the circuit
• ed by symvar as the summation index. If f is a constant, then the default variable is x
• The general prescription for expansion in a basis is illustrated by the Fourier series method. In the present case, our basis is the set of all Legendre polynomials, P n (x).Then, if f(x) is an arbitrary function in -1<x<1, we write the Legendre series: .To find the coefficients, multiply both sides by P n (x) and integrate over x.Due to the orthogonality and norms of the Legendre polynomials.
