**Text:** A current of 2.18 A is observed flowing through the cell for a period of 2.95 h. Calculate the amount of charge flowing through the circuit during this time. --- **Explanation:** This text is a problem statement commonly found in physics courses related to electricity. The task is to calculate the amount of electric charge (Q) that flows through a circuit when a known current (I) flows over a specified time period (t). In this case, a current of 2.18 amperes (A) flows for 2.95 hours (h). **Calculation:** To solve the problem, we use the formula: \[ Q = I \times t \] Where: - \( Q \) is the charge in coulombs (C), - \( I \) is the current in amperes (A), - \( t \) is the time in seconds (s). First, convert the time from hours to seconds: \[ 2.95 \, \text{hours} = 2.95 \times 3600 \, \text{seconds} \] Calculate the charge: \[ Q = 2.18 \, \text{A} \times 2.95 \times 3600 \, \text{s} \] \[ Q = 2.18 \times 10620 \, \text{C} \] \[ Q = \text{Calculate the final result for precise charge.} \]
