What effect does connecting batteries in series have on voltage?

• A. Increases the voltage
• B. Decreases the voltage
• C. No effect on voltage
• D. Increases the current

Answer: (A)

Connecting batteries in series increases the total voltage available in the circuit. When two or more batteries are connected in this configuration, their individual voltages add together. For instance, if two 1.5-volt batteries are connected in series, the total voltage supplied to the circuit becomes 3 volts. This is a crucial principle in electrical circuits where higher voltage is needed for devices that require more power to operate. In contrast, the current remains the same across all batteries in a series connection. This is an important aspect of series connections; while voltage increases, the current capability does not change based on the series arrangement.
