A practical battery has an internal resistance of 0.2 ohm. If this practical battery provides a power of 25 watts to a load with resistance 10 ohms, find: a. the power being consumed by the internal resistance of the battery: b. the terminal voltage across the battery if it were to be disconnected from the circuit;
