प्रश्न
State Kirchhoff ’s voltage rule.
Advertisements
उत्तर
It states that in a closed circuit the algebraic sum of the products of the current and resistance of each part of the circuit is equal to the total emf included in the circuit. This rule follows from the law of conservation of energy for an isolated system.
