Calculo passo a passo divisor de tensao
Por favor algum professor de matematica responda como calcular passo a passo essa equação e se esse professor residir em sp-capital quanto é sua hora aula.
V2 = [R2 / (R1+R2)] x V
para v2 = 5V
e R1 = 10Kohm
e V até 25V
sendo divisor de tensao por 5
eu também preciso de algumas aulas particulares de matematica, logo, o professor que responder se der aula particular a um valor acessivel por favor deixar contato

Answer #1
Sendo divisor de tensão por 5,
onde V2 a tensão de saída e V a tensão de entrada, temos:
V2=Vx(1/5).
Para V2=5 volts, temos que:
5=Vx(1/5)
V=25 volts
E que:
V2 = [R2 / (R1+R2)] x V.
Logo:
5=[R2/(10000+R2)] x 25.
Assim:
1=[R2/(10000+R2)] x 5
5R2=10000+R2
4R2=10000
R2=2,5K?
