What does the Android notification icon in Fig. 5 signify? What is the battery's actual capacity if it delivers 0.2 A for 5 hours and has a rated capacity of 2000 mAh?

Step 1: Analyze Question 25. The question provides the rated capacity of a battery and its actual discharge performance. • Rated battery capacity: 2000 mAh • Current delivered: 0.2 A • Time delivered: 5 hours First, convert the current from Amperes to milliAmperes: 0.2 A = 0.2 × 1000 mA = 200 mA Next, calculate the total charge (capacity) delivered by the battery: Capacity delivered = Current × Time Capacity delivered = 200 mA × 5 hours = 1000 mAh The battery delivered 1000 mAh before being totally discharged, while its rated capacity is 2000 mAh. This means the battery delivered only half of its rated capacity. This indicates that the battery's actual capacity is significantly lower than its advertised capacity. Step 2: Conclude for Question 25. A significant reduction in actual capacity compared to rated capacity means the battery cells are degrading or getting weak. The correct option is B. B Step 3: Analyze Question 26. The question asks to identify the meaning of the Android notification icon shown in Fig. 5. • The icon displays a circle with an exclamation mark inside, often accompanied by a smaller dot. This is a standard Android notification icon. • This specific icon is widely recognized in Android to indicate a low storage warning or that the device's storage is full. It prompts the user to free up space. Step 4: Conclude for Question 26. Based on common Android notification icons, the icon in Fig. 5 implies low storage. The correct option is C.
