In order to obtain a maximum current from a combination of cells, we must join the cells in

Options

A. parallel combination
B. series combination
C. mixed combination
D. in any of the above combinations depending upon the relative values of external and internal resistance

Answer

To obtain a maximum current from a combination of cells, we must join the cells in parallel. Here’s a step-by-step explanation:

### Step 1: Understanding Current Flow
- Current is the flow of electric charge. The amount of current that can flow through a circuit depends on the voltage provided by the cells and the resistance in the circuit.

### Step 2: Analyzing Cell Configuration
- Cells can be connected in two main configurations: series and parallel.
- **Series Connection**: In a series connection, the total voltage is the sum of the voltages of each cell, but the current remains the same as that of a single cell.
- **Parallel Connection**: In a parallel connection, the voltage across each cell remains the same as that of a single cell, but the total current is the sum of the currents from each cell.

### Step 3: Maximizing Current
- To maximize the current, we need to ensure that the voltage remains constant while increasing the current. This is achieved by connecting the cells in parallel.
- In a parallel configuration, the effective current increases because each cell contributes its current to the total current flowing through the circuit.

### Step 4: Conclusion
- Therefore, to obtain a maximum current from a combination of cells, we must join the cells in parallel.

### Final Answer
To obtain a maximum current from a combination of cells, we must join the cells in **parallel**.
