Answer:
Step-by-step explanation:
The resistance column is correct.
I1 = I2 = I3 = I4 = 2 Amps
So all the currents are the same.
R = 110
I = 2 amps
V = ?
Vt = I * R
Vt = 2 * 110
Vt = 220
=============
V1 = 20 * 2 = 40 volts. That's 40 volts dropped from the right side of R1 to the left side.
V2 = 60 * 2 = 120 volts across the 60 ohm resistor
V3 = 30 * 2 = 60
Total voltage = 40 + 120 + 60
Total voltage = 220 which is just what it should be.
==========================
Power
P1 = V1 * I
P1 = 40 * 2
P1 = 80 watts
P2 = 120*2
P2 = 240
P3 = 60 * 2
P3 = 120
Total Power = 80 + 240 + 120
Total Power = 440
