The two light bulbs were first connected in series and then in parallel. In which case is the connection power higher if the bulbs were plugged into a network with a current strength of 200 mA?
When connected in series, the total resistance of the bulbs is 2 R, when connected in parallel, the total resistance is RJ2. Consequently, the power with parallel connection is four times less than with a series connection of bulbs.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
