How to take reading of ammeter and voltmeter
WebAnswer: Here we can analyze the circuit firs to find curr cirrent and voltages across element by relacing the ammeter and voltmeter by their resistance. Here i = i 1 + i 2 (1) KVL 1. ε = Ri 1 + R A i 1 + R 0 i. 12 V = 85.0 Ω x i 1 + 3.00 Ω x i 1 + 100 … WebFeb 4, 2015 · For example, since the RMS voltage of a sine wave will be proportional to its peak voltage divided by sqrt(2), a meter that measures peak voltage would scale its readings by a factor of about 0.707. Since average rectified voltage is about (2/pi) times peak voltage, a meter that measured average rectified voltage would scale by 1.11.

WebSolution. The correct option is D. 1.2A,6V. We can see that basically the three resistors are in parallel. So the circuit can be redrawn as. Therefore voltage drop across each resistance is same as the provided by the battery. Hence, voltmeter reading (V) = 6 V. The current through the ammeter is same as the current through the equivalent ...
WebAmmeters. Ammeters measure current. Current is measured in amps (amperes), A . 1A is quite large, so mA (milliamps) and µA (microamps) are often used. 1000mA = 1A, 1000µA = 1mA, 1000000µA = 1A. Ammeters are connected in series . To connect in series you must break the circuit and put the ammeter across the gap, as shown in the diagram.
