The Russian Civil War. After the overthrow of the Provisional Government on 7th November, 1917, the All-Russian Congress of Soviets met and handed over power to the Soviet Council of People's Commissars.
A voltmeter is used to measure potentials as shown in Figure 1. The voltmeter has two clips that are colored red and black. When the red clip is connected to the anode and the black clip is connected to the cathode, a positive voltage is detected as shown in Figure 1. If the clips are backwards, a negative voltage is detected. In order to practice using the voltmeter, you can measure the potential of a closed battery. Turn on the meter and if it is not set to voltage push the + button once or twice. 1) Measure the potential difference of a AA (1.5 V) battery.
In order to increase the voltage between a batteryâs terminals, you can place the cells in series. Series means stacking the cells end-to-end, connecting the anode of one to the cathode of the next. By connecting batteries in series, you increase the total voltage. Add the voltage of all the cells to determine the operating voltage. The capacity stays the same. In this example, four 1.5 V cells are connected in series. The voltage across the load is 6 V while the total set of batteries have a 2000 mAh capacity.
