2.4: How to Use an Ammeter to Measure Current
To avoid noisy measurements and stray capacitance, always connect the AC ammeter terminal to the terminal of the device that has the least amount of capacitance to ground. In the example shown in Figure 16, the LCUR (AC ammeter) connection is made to Pad 1 because it has less parasitic capacitance to common than Pad 2.
• Connect the ammeter between the two unconnected wire ends (the two that were hanging in mid-air). You are now assured of measuring current through the wire or …
(a) (b) State what is meant by the capacitance of a parallel plate capacitor. [2] A capacitor of capacitance C is connected into the circuit shown in Fig. 7.1 . sensitive ammeter Fig. 7.1 When the two-way switch is in position A, the capacitor is charged so that the
A meter designed to measure electrical current is popularly called an " ammeter " because the unit of measurement is "amps.". In ammeter …
A capacitor of capacitance 10 μF is connected to an AC source and an AC Ammeter, if the source voltage varies as V = 50√2 sin 100 t, the reading of the ammeter is (1) 70.7 mA (2) 7.07 mA (3) 50 mA (4) 5.0 mA

An alternating e.m.f. `e=50sqrt(2) sin(100 t)`, its connected to a capacitor `C=1 mu F`. Then the reading shown by the a.c. ammeter connected in the c asked Apr 3, 2020 in Physics by Maheshmukherjee (93.5k points) class-12 electromagnetic-induction ...
Capacitors are generally with two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, …
An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so it is a displacement current that the ammeter records. The value of this current is …
An alternating voltage e = `200sqrt2` sin(100 t) volt is connected to a 1 µF capacitor through a.c. ammeter. The reading of the ammeter is 20 mA. Explanation: Alternating voltage: e = `200sqrt2` sin(100 t) volt Comparing with e …
