WebThe resistance of a galvanometer is usually high and it takes very small amount of current to show full scale deflection. The various electric meters use resistors in series or in … WebA galvanometer is converted into a voltmeter by connecting high resistance Rh in series with galvanometer as shown in Figure 3.74. The scale is now calibrated in volt and the range of voltmeter depends on the values of the resistance connected in series i.e. the value of resistance is so adjusted that only current Ig produces full scale ...
WebApr 10, 2024 · Two sharp metal electrodes acting as sounders connected to the galvanometer were used to penetrate the organic tissues of the living animal, held firm by the legs by two laboratory assistants (Fig. 8). Thus, locked into the galvanometer circuit, the following organs were explored: heart, liver, brain, spinal cord, chest muscles, and thighs. WebExample 2: How an Unknown Resistor Must Be Connected. A circuit that can be used as an ohmmeter is shown. The circuit uses a galvanometer, a direct current source with a known voltage, a fixed resistor, and a variable resistor. The resistance of the variable resistor is adjusted until the galvanometer’s arm is at a full-scale deflection position.
