Answer: Elements in the same period have the same number of electron shells; moving across a period ( elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
Ohm's law states that the potential difference across a resistor is directly proportional to the current flowing through it:
![V=IR](https://tex.z-dn.net/?f=V%3DIR)
where
V is the potential difference
I is the current
R is the resistor
In our problem, the potential difference is the voltage of the battery, V=20 V, and the current flowing in the light bulb is I=0.57 A. By using Ohm's law, we can calculate the resistance of the light bulb:
