Uptill now we have analysed and studied the performance of DC supply and DC circuits. But 90% of electrical energy used now a days is a.c in nature. Electrical supply used for commercial purpose is alternating.
Steps for Solving Mesh Equation
Subject and UNIT: Basic Electrical, Electronics And Instrumentation Engineering: UNIT I: Electrical Circuits
Mesh analysis is a method that is used to solve planar circuits for the current at any place in the circuit. Planar circuits are that can be drawn on a plane surface with no wires crossing each other.

The rate at which electrical work is done in an electric circuit is called an electrical power or instantaneous power.
Subject and UNIT: Basic Electrical, Electronics And Instrumentation Engineering: UNIT I: Electrical Circuits
Kirchoff's current and voltage laws are used to systematically analyze the relationships between voltages and currents in a given electric circuit.
Limitations of Ohm's Law
Subject and UNIT: Basic Electrical, Electronics And Instrumentation Engineering: UNIT I: Electrical Circuits
Ohm's law states that in a linear network, at constant temperature the voltage across the conducting material is directly proportional to the current flowing through the material.
