A simple qn on physics electricity pls help!

Hello, can someone, anyone, teach me:
what does resistor do. (eg: limit the number of electrons???etc..) What is voltage The reistor doesnt affect the current? Why? -

the resistor affect the current when the circuit is connected in parallel..

lol ... lol...Originally posted by davidche:activity rating of 8..
it is not the quantity of replies tat matter
it is the quality of replies tat matter...
if u ask in chit chat, hmmm..... -
how so? care to elaborate?Originally posted by mr_sotong:the resistor affect the current when the circuit is connected in parallel.. -
i just did!Originally posted by Darkness_hacker99:It's still new, so we are trying to promote my forum. Our vision is to help people with their homework and let them understand how to solve their question. -
imagine the current as water...Originally posted by davidche:how so? care to elaborate? -
yeah. and the wires as pipes.Originally posted by mr_sotong:imagine the current as water... -
What you mean resistor don't affect the current?
V = RI what. -
homework forum got 3 reply that are all much better than the replies here. dont judge a forum by its activity rating.

Resistor limits current, higher resistor lower current for the same amount of voltage...Originally posted by davidche:Hello, can someone, anyone, teach me: what does resistor do. (eg: limit the number of electrons???etc..) What is voltage The reistor doesnt affect the current? Why?
V=IR, that is if there is only real power...
Voltage is electric potential energy per unit charge...
Resistor limits the current so it affect the current... if will only not affect the current if theres a open circuit at the resistor... of cause if it is an open circuit then the resistance of that path can said to be infinity thus no current will flow through it... example : during parallel circuit, more current flow through the smallest resistance and less current flow through the largest resistance... -

thanks...
