You have a battery marked "6.00 V." When you draw a current of 0.387 Afrom it, the potential difference between its terminals is 5.25 V. What is the potential difference Δ? when you draw 0.583 A?

A heart defibrillator is used to enable the heart to start beating if it has stopped. This is done by passing a large current of 12 A through the body at 25 V for a very short time, usually about 3 milliseconds. How much energy is transferred from the defibrillator to the body? O 0.90 J O 300 J O900 J O 0.30 J
