can some one helpp me????

Question

anonymous · Answer

Alike - they both contain electrical components
Different - resistances in parallel circuits are summed differently to resistances in series circuits

anonymous · Answer

Series circuit: $$R_{total} = \sum_{n}^{} R_n$$Parallel circuit: $$\frac{ 1 }{ R_{total} }  = \sum_{n}^{n}\frac{ 1 }{ R_n }$$

anonymous · Answer

If I can, sure.

anonymous · Answer

I is current, V is voltage and R is resistance. If the resistance decreased then it would follow that the current would increase as you would be dividing the same voltage with a smaller number.

anonymous · Answer

The resistance of a material is a its opposition to the flow of electric current, measured in ohms.
The amount of current flowing through the light bulb would increase as a result of the voltage increase which would cause it to glow brighter before burning out.

No problem, glad to be of help.
