Construction of voltmeter
WebApr 1, 2024 · Here is the construction of a second cluster with the two remaining cell duets, again using the wooden holding fixture and rubber bands. Total Voltage = 1.25V x number of cells There are four cells in the second cluster, so the total voltage should be about 5V. The DVM in Figure 8 measures 5.17 volts, indicating the cluster is correctly wired. WebThe voltmeter is placed in parallel with the component of interest because components in parallel experience the same potential difference. For example, if we want to measure the electric potential drop across resistor R 2 R_2 R 2 R, start subscript, 2, end subscript , the voltmeter should be arranged in parallel with the resistor ( R 2 R_2 R 2 ...
