It took me a while to find out what a star connection is. In the US we call it a Y connection. Each resistor has to dissipate 1/3 of the power, or 5000 watts. then it's just a case of using P=E2/R. or R =E2/P R = 208 x 208 / 5000 = 8.66 ohms
If the resistor is conducting electrical current, then the power it dissipates (heat energy per second) is(current through it)2 times (22,000)or(voltage across it)2 divided by (22,000).If the resistor is connected in an unpowered circuit, or stored in a drawer, then it dissipates zero heat.
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
Even though it is connected to a 9 volt source, it is still a resistor.
Since they're connected in parallel directly across the source, the voltages across both componentsare equal, and are equal to the source, i.e. 120 v DC.
A typical resistor will burn out when it dissipates power in excess of double its power dissipation rating for an extended period of time. The power dissipated by a resistor is equal to I2R or E2/R, where E = the voltage across the resistor I = the current through the resistor R = the resistance of the resistor

A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
A resistor is used to reduce current flow, and will also act to lower voltage levels in a circuit. It also dissipates heat.
it should hav a heat sink built in to disapate the heat!
Divide the voltage

I'd have to see a diagram, as your description in words is unclear.
Internal resistance is approximately equal to 94.667
