Hey!!!
Today we learnt about Series Circuit...
Do you know what will happen if resistors are connected in Series.....???
It will start to have :
. Overall resistance increases....
. Current decreases
. Bulb is dimmer....
(Less bright)


Next is Parallel Circuit...

:Parallel circuit has more than one path for current to flow....

:Current from battery=sum of current in separate paths....

: Voltages are equal across the branches....

Hm...

Let's see, there are two bridges connected in parallel...

If one of the bridges breaks, can the runner still reach the other side...???

Well, the answer is YES!

The advantage:

-Current become bigger....

-If lightbulb cannot work, the other lightbulb still light up...

But WAIIIIIIIIIIT...

Series circuit has only ONE path for current to flow unlike the parallel circuit...

Current is the same at any point....

Total resistance for two resistors in series are:

R=R1+R2
