A 20 Ω resistor is connected in series with an inductor, a capacitor and an ammeter across a 25 V variable frequency supply. When the frequency is 400 Hz, the current is at its maximum value of 0.5 A and the potential difference across the capacitor is 150 V ii.
Ammeter
Thus the loading effect of the ammeter when connected in series with the circuit component whose current is to be measured is greatly reduced. Ideally, the ammeter''s total resistance would be zero. As shunt resistors used for ammeters have resistive values which are very low, usually they have to be made from relatively large-diameter wire, or solid pieces of …
Capacitors in Series and Series Capacitor Circuits
Since Kirchhoff''s voltage law applies to this and every series connected circuit, the total sum of the individual voltage drops will be equal in value to the supply voltage, V S.Then 8.16 + 3.84 = 12V. Note also that if the capacitor values are the same, 47nF in our first example, the supply voltage will be divided equally across each capacitor as shown.
Ammeter uses a galvanometer and a shunt, connected in parallel: A I ⇒ Everything inside the green box is the ammeter. • Current I gets split into I shunt and I G Homework hint: If your galvanometer reads 1A full scale but you want the ammeter to read 5A full scale

The ammeter is connected in series with the component in question. Ammeters need to have a very low resistance, a fraction of a milliohm. If the resistance is not negligible, placing the ammeter in the circuit would change the equivalent resistance of the circuit and modify the current that is being measured.
