Natuurkunde Les 4
Vermogen (P) -> hoeveel elektrische energie een apparaat per seconde verbruikt
De eenheid van vermogen (P) is Watt (W)
Een klein vermogen betekent dat er weinig elektrische energie per seconde verbruikt
wordt. Een groot vermogen betekent dat er veel elektrische energie per seconde
verbruikt wordt.
Formule: P = U X I
P
Vermogen = P in watt
Spanning = U in volt
Stroomsterkte = I in ampère
UXI

U=P:I
I=P:U
P=UxI
P=UxI
Spanning (U) = 230 V
Stroomsterkte (I) = 0,28 A
Vermogen = 230 X 0,28 = 6,44




P=UxI
P = 110 watt
U = 230 volt
I=P:U
I = 110 : 230 = 0,478
4,78 x 10^-2
