A 3.3 kΩ resistor dissipates 0.25 W. the current is 8.7 mA.
Power loss in a resistor (P) =I2.R
Where, I is the current
R is the resistance
P is the power loss. Always power loss in a resistor takes place in the form of heat energy.
Given Resistance = 3.3 KΩ
Power loss = 0.25 Watt
Current i=√(0.25/3300)=8.7 mA
