Question

Daya yang terpakai pada sumber sebesar...

_______|E=6V, r=0.5ohm|_______
| |
| |
|__________{2,5 Ohm}__________|

Answer 1

V nya 5v
i=5/2,5=2
p=vi
p=10 watt

Answer 2

I = E / R+r
  = 6 / 0,5 + 2,5
  = 6 / 3
  = 2 A
V = E - I.r
   = 6 - 2 . 0,5
   = 6 - 1
   = 5 Volt
P = V . I
   = 5 . 2
   = 10 Watt
