The document discusses three exercises involving voltage and current dividers. In the first exercise, it calculates the total resistance, input current, and currents through each resistor in a three-resistor divider. The second exercise does the same for a two-stage divider. It finds the equivalent resistances and input/output currents. The third exercise calculates the total resistance and input current for a three-resistor divider, then uses ohm's law to determine the voltages across each resistor.

Req= 1 = 4.61ohm
1/10 + 1/20 + 1/15
I = E/Req = 100 V/4.61 ohm = 22A
I1 = E/R1 = 100 V/10 ohm = 10A
I2 = E/R2 = 100 V/20 ohm = 5A
I3 = E/R3 = 100 V/15 ohm = 7A

R12 = 1 = 10ohm
1/20 + 1/20
R34 = 1 = 20ohm
1/40 + 1/40
Rt = R12 * R34 = 10 * 20 = 6.66 ohm
R12+R34 10+20
I = E / Rt = 100 V / 6.66 ohm = 15.01A

I1 = R2 * I = 20 * 15.01A = 10A
R1+R2 10+20
I2 = R1 * I = 10 * 15.01A = 5A
R1+R2 10+20

Rt = R1 + R2 +R3
Rt = 70ohm + 35ohm + 100ohm = 205ohm
I = 100 V / 205ohm = 0.48A
V1 = 0.48 A * 70 ohm = 34 V
V2 = 0.48 A * 35 ohm = 17 V
V3 = 0.48 A * 100 ohm = 48 V
