Ohms Law,Series and Parallel circuits, Kirchoff's Current Law(KCL),Kirchoff's voltage Law(KVL),power equation,

Ohms Law: If temperature and other physical condition remain constant, then power flow through the conductor is directly proportional to the potential difference. Kirchoff's current Law:(KCL) The algebraic sum of current meeting at any point is zero in any closed network. Kirchoff's voltage Law:(KVL) The algebraic sum of voltage drop+The induced emf is zero in any closed network. Power Equation:- We know that,P=IE...........(i) As per Ohms law,we know that,I=E/R Combined with power equation, P=IE We get ,P=E(E/R) Or,P=E^2/R,from ohms law we know that E=IR,combine this with P=IE,we get,P= I^2R.

ELECTRICAL ENERGY

Electrical Energy:-  Electrical energy is the work done by Electric charge,If current flows through the conductor or through any other conductive element of potential difference across it,for time 't' second, then the electric charge is- e=vit joules , Whare,v=voltage, I=current, t=time Electrical Energy- P=vi watts. Watt Hours (w-h):- If one watt power is being consumed for 1hour time,the energy consumed is one w-h(watt-hour).

Besic Electrical circuit concept

Resistance - Resistance is the one type of equipment which maybe defined as the property of a substance which opposes the flow of current. Inductance - Inductance is the property of materials by virtue of which it opposes any change of magnitude or direction of current passing through the conductor. Capacitance - Capacitance is the property of capacitor to store electricity may be called its capacitance. <>The resistance of a conductor depends upon- i)  ii ) Its depends on the nature of the materials. iii )Temperature of the conductor.
