The question in the image asks for the power consumed by a calculator with a current of 0.02 A and a potential difference of 18 V.

To solve this, we use the formula for electrical power:

\[
P = V \times I
\]

Where:
- \(P\) is the power (in watts),
- \(V\) is the voltage (in volts),
- \(I\) is the current (in amperes).

Given:
- \(V = 18 \, \text{V}\)
- \(I = 0.02 \, \text{A}\)

Now let's calculate:

\[
P = 18 \, \text{V} \times 0.02 \, \text{A} = 0.36 \, \text{W}
\]

Thus, the correct answer is **B. 0.36 W**.

Here are 5 related questions to explore:
1. How is electrical power related to voltage and current in a circuit?
2. What other formula can be used to calculate power if resistance is known?
3. What happens to power consumption if the current is doubled while keeping voltage constant?
4. Can power be negative in a circuit? If yes, what does it mean?
5. How is power efficiency calculated in electrical devices?

**Tip:** Remember that in a direct current (DC) circuit, power is the product of voltage and current, making it easy to calculate using \( P = V \times I \).
