Three dry cells are connected first in series and then in parallel. The individual cells have voltages of 1.5 V, 1.8 V, and 2.0 V. Calculate the total voltage of the cells when they are connected in series and then when they are connected in parallel.

Cells connected in series gives a final voltage that is the sum of the individual cell voltages.

To calculate the total voltage of the cells when they are connected in series, you simply add up the voltages of the individual cells.

Given that the individual cell voltages are 1.5 V, 1.8 V, and 2.0 V, the total voltage when connected in series would be:

Total voltage in series = 1.5 V + 1.8 V + 2.0 V = 5.3 V

When the three dry cells are connected in series, the total voltage is 5.3 V.

To calculate the total voltage of the cells when they are connected in parallel, you need to find the voltage of the individual cells.

Given that the individual cell voltages are 1.5 V, 1.8 V, and 2.0 V, the total voltage when connected in parallel would be the same as the highest voltage among the individual cells, which is 2.0 V.

So, when the three dry cells are connected in parallel, the total voltage is 2.0 V.

To calculate the total voltage when the cells are connected in series, you need to add up the individual voltages of the cells.

The cells have voltages of 1.5 V, 1.8 V, and 2.0 V. When connected in series, the total voltage is obtained by adding these voltages together:

Total Voltage (Series) = 1.5 V + 1.8 V + 2.0 V

Now, let's calculate the total voltage when the cells are connected in parallel. When cells are connected in parallel, the voltage across each cell remains the same, and the total voltage is the same as the voltage of the individual cell with the highest voltage.

Total Voltage (Parallel) = Maximum Voltage among the individual cells

In this case, the highest voltage is 2.0 V, so the total voltage when the cells are connected in parallel would be 2.0 V.

Therefore, the total voltage of the cells when they are connected in series is 1.5 V + 1.8 V + 2.0 V = 5.3 V, and when they are connected in parallel, the total voltage is 2.0 V.
