WWW.VIDYARTHIPLUS.COM KIRCHOFF’S VOLTAGE LAW EX. NO: 1(a) AIM: To verify the Kirchoff’s Voltage Law (KVL) for the given circuit. APPARATUS REQUIRED: S.NO APPARATUS 1 RPS 2 Resistor 3 Voltmeter 4 5 TYPE RANGE QUANTITY DC (0-30)V 1 - 1KΩ 3 DC (0-10)V 3 Bread board - - 1 Connecting wires - - Few FORMULA USED: 1. CURRENT DIVISION RULE: I = TOTAL CURRENT X OPPOSITE RESISTANCE TOTAL RESISTANCE 2. OHM’S LAW: V=IR Where, V = Voltage in Volts I = Current in Amperes R = Resister in Ohms THEORY: KIRCHOFF’S VOLTAGE LAW: It states that the algebraic sum of all the voltages in a closed loop is equal to zero. ∑V = 0 V+ TEAM
