The unit of battery capacity is MAH, and the visible capacity is expressed in terms of the amount of electricity (charge) that the battery can provide. Q=IT

When connected in parallel: the voltage is 1.5V and the total capacity is 2400MAH. I won't analyze this, just think about it myself

When connected in series: the voltage is 3V; Although two batteries can perform twice as much electricity as one battery, according to W=UIT and 2W=(2U) IT, it can be seen that the product of IT remains unchanged when two batteries are connected in series, that is, the amount of electricity provided remains unchanged. So the total capacity is 1200MAH

The series voltage is added together, and the capacity remains unchanged; The parallel capacity is added together, and the voltage remains unchanged.

When batteries of the same capacity are connected in series, the voltage increases and the capacity remains unchanged. When batteries of different capacities are connected in series, the voltage is added up and the capacity is calculated as small (this method is not recommended, otherwise it will cause overcharging and discharging of small capacity batteries and premature damage)

Calculated based on 24V: A current of 60W is 60/24=2.5A, and the required ampere hours are 2.5 * 12 * 3=90AH

The unit of battery capacity is MAH, and the visible capacity is expressed in terms of the amount of electricity (charge) that the battery can provide. Q=IT

When connected in parallel: the voltage is 1.5V and the total capacity is 2400MAH. I won't analyze this, just think about it myself

When connected in series: the voltage is 3V; Although two batteries can perform twice as much electricity as one battery, according to W=UIT and 2W=(2U) IT, it can be seen that the product of IT remains unchanged when two batteries are connected in series, that is, the amount of electricity provided remains unchanged. So the total capacity is 1200MAH

Parallel connection: Several batteries, positive and positive, negative and negative connected side by side, with the same voltage and increased capacity, corresponding to an increase in current. Series connection: Several battery heads and tails are connected together, which is positive and negative. The negative in the first section is connected to the positive in the second section, and so on. As the voltage increases, the capacity remains unchanged. That is to say, if connected in series, the electromotive force is the sum of the electromotive forces of two batteries. If connected in parallel, the voltage they provide to the electrical appliances is only as large as the electromotive force of one battery. I hope my answer can help you! I am also learning this part of the knowledge, it is difficult, I need to work hard! Wishing you success in your studies!
