To solve the problem of calculating the amount of heat produced in the battery in 20 seconds when a current of 30 A is flowing through a dry cell with an emf of 1.5 V, we can follow these steps: ### Step 1: Understand the Formula for Heat Produced The heat produced (H) in a resistor due to current can be calculated using the formula: \[ H = I^2 R t \] where: - \( H \) = heat produced (in joules) - \( I \) = current (in amperes) ...
