If the current flowing trough a 10 ohm resistor is 15 mA the power consumed in the resistor is?

The power consumed in a resistor can be calculated using the formula ( P = I^2 R ), where ( P ) is power, ( I ) is current, and ( R ) is resistance. In this case, with a current of 15 mA (or 0.015 A) flowing through a 10 ohm resistor, the power consumed is ( P = (0.015)^2 \times 10 = 0.00225 \times 10 = 0.0225 ) watts or 22.5 mW.
