Detailed Solution
Download Solution PDFKirchhoff's Voltage Law (KVL)
It states that "In a closed loop of an electric circuit, the algebraic sum of the EMFS is equal to the algebraic sum of the potential drops".
\(\Sigma V=0\)
\(-V+V_1+V_2=0\)
\(V_1+V_2=V\)
Kirchhoff's Current Law (KCL)
It states that the algebraic sum of currents entering a node is equal to the algebraic sum of currents leaving a node.
\(\Sigma I_i=\Sigma I_o\)
\(I_1+I_2+I_3=I_4+I_5\)
Ohm's Law
Ohm's law states that the current through a conductor is directly proportional to the voltage applied across it, provided the temperature remains constant.
V = I × R
Lenz Law
Lenz's Law states that the direction of an induced current is such that it opposes the change in magnetic flux that caused it. This is a consequence of the conservation of energy and Faraday’s Law of Electromagnetic Induction.
\(E=-{d\phi \over dt}\)
