Question

1. Dado o circuito abaixo determine:

a) Req = ?

b) It = ?

c) Pt ?​

Answer 1

Resposta:

a)

Req = 2/3 Ohm

b)

It = 15/2 A

c)

Pot = 75/2 W

Explicação:

Req1 = 2.4/(2+4) = 8/6 Ohms

Req2 = Req1 = 8/6 Ohms

Req = Req1.Req2/(Req1 + Req2)

Req =( 64/36)/(16/6) = 2/3 Ohms

b)

It = U/Req

It = 5/(2/3) = 15/2 A

c)

Pot = U.It = 5.(15/2) = 75/2 W
