AI Generated Solution

To find the rate at which energy is being dissipated as heat inside the battery, we can use the formula for power dissipated due to resistance in an electrical circuit. The power (P) dissipated in a resistor can be calculated using the formula: \[ P = I^2 R \] Where: - \( P \) is the power in watts (W), - \( I \) is the current in amperes (A), - \( R \) is the resistance in ohms (Ω). ...
