Problem 6

Given information

There are two identical batteries and two tubelights. It is required to build a circuit where the power of the tubelights is maximum.

Step-by-step explanation

The power of any device is defined as, Power,  . Where V is the voltage and R is resistance. Thus, according to this formula, to obtain maximum power it is required that the value of voltage(V) is as large as possible and the value resistance (R) is as small as possible.
