Asked by fatih

a 100 V DC signal is applied to four resistors as shown in Fig. 5. The values of the resistors are 20 ohm, 40 ohm, 60 ohm and 80 ohm. What is the voltage across the 40 ohm resistor?

E = 100 Vdc
R1 = 20 Ohms
R2 = 40 Ohms
R3 = 60 Ohms
R4 = 80 Ohms
V2 = ?

If the resistors are connected in series,

I = E/(R1+R2+R3+R4)

V2 = I*R2
