With two identical light bulbs and two identical batteries how would you arrange in order to get the maximum total power to the light bulbs?

The batteries would be connected in series while the bulbs would be connected in parallel

Explanation:

Power (W) = VI

where V = voltage, I = current and R = resistance

from V = IR , I = V/R

Power (W) now becomes = V (V/R) =

Power (W) =  

from the above equation, power is directly dependent on voltage, hence the voltage has to be high for the power to be high and the power is also inversely dependent on the resistance (in this case the bulbs which act as the load)

Take note that the power from this connection should not exceed the bulbs power rating so as to avoid damage of the bulbs.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

compass can be used day and night, cloudy or sunny
