re 2. Cireuit used for Question 3. .4?, and Rs-1.7? ifthe terminal voltage ofthe battery is SS V, alaa, A) Physics B Postlab Quiz Ohm's Law 31. Which device would you choose to measure electrica (A) Ammeter D) Volmetce 0) T 2. In Graph I, the experimenital values of voltage are ploned through the resistance Determsine the value of the resistance fran the value of the resistance from Te Trom the gah (B) 5.2 (C) 150 D) 0.14 0 (A) 4 Veltage vs. Current 70 Current (A) Graph 1: Voltage and Current measurenments 110 33. Calculate a current in a 470 ? resistor when a potential difference of 60 V is applied across is (C) 13 A (D) 13 mA (A) 78 A (B) 78 mA 34. If the potential difference across the ends of a wire and the length of the wi will be deubled at the same time, how will it change the current passing through the wire? (A) There will be no change in the current passing through the wire. (B) The current passing through the wire will be doubled. (C) The current passing through the wire will be halved. D) The current passing through the wire will be quadrupled (E) There will be a 4x drop in the current passing through the wire. 35. The overall resistance of a humar is a perception level when humans just start to sense a slight tingling, while a 5mA current produces a strong im potential difference that will cause the involuntary reaction in a human bod (C) 10 V Calculate the y. (A) 500 V (B) 50 V (D) 2 V E) IVExplanation / Answer
Q1.
Ans- (C) Ohmmeter
electrical resistance is mesured using ohmmeter.
Voltmeter is ued to measure Potential difference.
Ammeter and galvanometer are ued to measure electric current.
thermometer is ued to measure temprature.
So correct option is (C) ohmmeter
