Really need the explanation PLZZZ  ???

find the total current: to find dat I=V/R
total voltage n total current
total resistance = 6
total voltae = 3
so....3/6= 2(total I)
 LOSS VOLTAGE = Ir
0.5x2
so the votage delivrd is 2 n power will b VxI so 2x0.5 = 1
this is for m/j 07
tried my best explain hope it helps

Joseph_COOL:
thanks 274 sports :D
u did ur best and it was more than enough :D
got the idea :D :D

Allyza1n:
hey
im very confused in interference

x = lambda * distance/ slit seperation

so;
when do the fringes appear blured?
when does the intensity increase?
when does the distance increase?
what happens if you use a monochromatic source of light?

thanks in advance :)
