Question

calcule o resistor equivalente a associação de resistores apresentada na figura ao lado

Answer 1

5)

req= R1+R2+r3
req=4+5+6= 15ohms

6)
req= R1+R2+r3
req=22+240+20
req= 282ohms

7)
req= R1+R2+r3+r4
28= R1+10+4+6
28= R1+20
28-20= R1
R1= 8ohms

req= 6/6
req= 1ohm


10)

RT= R/n

RT= 10/5
Rt= 2 ohms
