Practicum Natuurkunde H3 Samenvatting


Voltmeter


De V-meter sluit je aan over een lampje of component (parallel). Hij staat dus altijd parallel
geschakeld. Je gebruikt de gele snoeren.


Ampere meter

Een spanningsbron (batterij of voedingskastje) zorgt voor het rondstromen van de elektronen in een
gesloten stroomkring. Deze elektrische stroom meten we met een Ampèremeter.

Bij het aansluiten van de Amperemeter gelden de volgende regels

 De meter moet in de stroomkring geplaatst worden → in serie

 Je gebruikt altijd 1 van de rode aansluitpunten als ingang, het zwarte aansluitpunt als uitgang




Formules


R= U : I
G= I : U R= 1 : G
U= I x R
I= G x U G= 1 : R
I= U : R
U= I : G



Parallelschakeling



Ubron= U1 = U2 (= U3….)

Ibron= I1 + I2 (+ I3….) Naamgeving



U → Spanning in Volt (V)
Serieschakeling I → Stroomsterkte in Ampere (A)

R → Weerstand in Ohm (Ω)
Ubron= U1 + U2 (+U3…) G → Geleidbaarheid in Siemens (S)
Ibron= I1 = I2 (= I3….)
