legea lui Ohm +tabel 1.2 (rezisivitate)
R=U/I =>I=U/(R+r) I=1.5/1+0.2 I=1.25A R=ro*l/S(tabel 1.2 elem chimice) ex: ce rezistenta are un fir de cupru de 10 m si o sect. transv. de 1mm^2?…
Teaching with circuits?
Create a classroom, give your students a circuit to build, and review what they submit.
See classroom plansHow it works
R=U/I
=>I=U/(R+r)
I=1.5/1+0.2
I=1.25A
R=ro*l/S(tabel 1.2 elem chimice)
ex: ce rezistenta are un fir de cupru de 10 m si o sect. transv. de 1mm^2?
roCu=16.7*10^-8
=>R=16.7*10^-8 *10/1=0.167[Ohm]
