# Is Connected To Opposite Ends Of The Ammeter The Circuit Is Closed                                                  ## Is Connected To Opposite Ends Of The Ammeter The Circuit Is Closed

Closed-When the term closed is used in relation to an electrical circuit it means that current can flow or it has continuity. Infinity ohms-This is what an ohmmeter reads when placed on an open circuit. On an analog meter infinity ohms is when the needle doesn't move at all and on a digital meter infinity ohms is 1 .

1. CIRCUITS WITH RESISTORS, BATTERIES, AMMETERS AND VOLTMETERS when we ﬁll the pipe with a granular material, e.g. coarse sand). Pursuing the analogy, the resistance R= V/Icorresponds to the ratio of the height ﬀ h, and water ﬂux.According

An instrument called ammeter measures electric current in a circuit. It is always connected in series in a circuit through which the current is to be measured. Figure 12.1 shows the schematic diagram of a typical electric circuit comprising a cell, an electric bulb, an ammeter and a plug key. Note that the electric current flows in the circuit

required, to 3.0 V with circuit closed. Otherwise, the voltage drop in the power supply may yield significantly less than 3 V to the external circuit.) Open the switch and move the ammeter in the circuit to a posifon "after" a resistor [i.e., on the opposite side of the resistor from the voltage source so as to measure the current flowing

1. CIRCUITS WITH RESISTORS, BATTERIES, AMMETERS AND VOLTMETERS For water flow in a narrow pipe, the drag force is propor-tional to the flow speed and to the pipe lengthl, i.e. k= κl. For ordinary pipes, the drag force (and hence, the coefficient

The reasons for this are specific to ammeter design and operation. When measuring circuit current by placing the meter directly in the path of the current, it is best to have the meter offer little or no resistance to current flow. Otherwise, the additional resistance will alter the circuit’s operation.

Ωis connected to the rails at points a and b, directly opposite each other. (The wheels make good electrical contact with the rails, and so the axle, rails, and R form a closed-loop circuit. The only significant resistance in the circuit is R. ) A uniform magnetic field B = 0.080 0 T is vertically downward.

In resistive circuits,when you need the same current in the whole circuit,you use series circuit because in series circuit current remains the same.If you have two batteries of 12 volts each,and ...
