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

How much amount of heat will produce in 22kilo ohm resistor?

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 resistor and a capacitor are connected in parallel across a 120 v dc source determine the voltages across the resistor and the capacitor?

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.


At what level will typical resistors burn out?

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
