When Solar Cells are connected in seriesa.It increases the bothb. It increases the voltagec. It increases the current

When solar cells are connected in series, it increases the voltage.

Here's a step-by-step explanation:

1. A solar cell is a device that converts light energy directly into electrical energy. Each solar cell produces a small amount of voltage (around 0.5V for silicon cells).

2. When you connect solar cells in series, you add up the voltage of each cell. For example, if you connect two solar cells in series, each with a voltage of 0.5V, the total voltage would be 1V.

3. The current, however, remains the same. This is because in a series circuit, the current is the same at all points in the circuit.

So, the correct answer is b. It increases the voltage.
