Step 1: Identify the given values. The energy required to charge the phone is 14.8 Wh. From the previous problem, the power output of the charging device (S20 3) is 1.5 W. Step 2: Use the formula relating energy, power, and time. The formula for energy is: E = P × t where E is energy, P is power, and t is time. Step 3: Rearrange the formula to solve for time. To find the time, we can rearrange the formula: t = (E)/(P) Step 4: Substitute the given values and calculate the time. t = 14.8 Wh1.5 W t ≈ 9.8666 h Step 5: Round the answer to a reasonable number of decimal places. t ≈ 9.87 h The final answer is 9.87 h.
