As each resistance is removed from the circuit, total resistance increases.
By
Ohm's law, as resistance increases with voltage remaining constant, current
decreases.

b--para 6b
Since resistor B in parallel with series resistors V and W yield a
parallel resistance of 5 ohms, the 10-volt source voltage will be divided equally
between resistors A and B.

P = I2R = 52 x 150
P = 25 x 150 = 3,750 watts
