When an a.c source is connected across a resistor

An ac source is connected across a resistance of 10 Omega The power dissipated in the resistor is 100W The rms valuse of the current and voltge are .

When a battery connected across a resistor of 16 Omega , the voltage across the resistor is 12 V. When the same battery is connected across a resistor of 10 Omega , voltage across it is 11 V. The internal resistance of the battery (in ohm) is
