Task data: R (resistance of the used resistor) = 18 Ohm; P (current power) = 0.6 W.

We express the current strength in the resistor used from the formula: P = I2 * R, whence I = √ (P / R).

Let’s perform the calculation: I = √ (0.6 / 18) ≈ 0.18 A.

Answer: The current in the used resistor is 0.18 A.
