Answer:

0.18 watt

Explanation:

The following data were obtained from the question:

Current (I) = 0.1 A

Resistance (R) = 18 ohms

Power (P) =.?

P = I²R

Where

P is the power.

I is the current in the circuit.

R is the resistance.

With the above formula, we can obtain the power in the circuit as follow:

P = 0.1² × 18

P = 0.01 × 18

P = 0.18 watt

Therefore, the power in the circuit is 0.18 watt
