WebMar 11, 2024 · This is very different to "the emf in a circuit (a loop) is simply the sum of the individual emfs". The 2 rules/methods bear no resemblance with each other, the first has a condition (that there is no load or current), the second one just says emf in a circuit is just the sum of individual emfs. WebTotal resistance of the circuit = 2 80 + 20 = 60 Ω ⇒ Main current, i = 60 2 = 30 1 A Combination of voltmeter and 80 Ω resistance is connected in series with 20 Ω, so current through 20 Ω and this combination will be same, i.e., 30 1 A.
