If two 1.5-V alkaline batteries are connected in series in a TV remote, what total voltage do they supply?

• A. 1.5 volts
• B. 3 volts
• C. 6 volts
• D. 4.5 volts

Answer: (B)

When two 1.5-V alkaline batteries are connected in series, their voltages combine to increase the total voltage supplied to the device—in this case, a TV remote. In a series connection, the positive terminal of the first battery is connected to the negative terminal of the second battery, effectively creating a single path for electrical current while adding their voltages together.

So, if each battery provides 1.5 volts, by placing them in series, you can simply add the two voltages together: 1.5 V + 1.5 V equals 3 volts. This total voltage of 3 volts is what the remote control would utilize for operation. Therefore, the configuration of the batteries directly supports the total voltage calculation in a series arrangement.
