To find the internal resistance of the battery, we will follow these steps: ### Step 1: Calculate the current for each resistance using the power formula. The power \( P \) supplied to a resistor \( R \) is given by the formula: \[ P = I^2 R \] For the first resistance of \( 6 \Omega \) with power \( 150 W \): ...
