Answer:
See attached file.
Explanation:
See attached file for detailed code.
Since resistance and current are inversely proportional, when the resistance doubles, the current is cut in half.
In a parallel connection, the voltage is same in every branch.
Now, three <span>three resistors connected in parallel.
R1 = 2k ohm
</span>R2 = 6k ohm
R3 = 10k ohm
in parallel, net resisitance =

Now, putting the values, we get, R net = 1.30 k ohm.
Ans, voltage = 100 VDC
Thus, power =
= 7.69 Watt
