When you first connect a capacitor to a working circuit, no charge has built up across the plates, so the capacitor allows charges to flow freely. After a long time, the capacitor has built up its maximum charge, and no more current will flow onto the device. Which equation or theory is this based on?

Which of the following is the correct physical explanation for the dangers posed by large currents passing through the human body? Question 14 options: The energy delivered during electrocution is proportional to the amount of current. The number of protons passing through the body from electrocution is dangerous. The resistive heating that occurs from electrocution is proportional to the amount of current. The large current absorbs a lot of heat from the body as it passes through tissues.
In the Electric Field Mapping experiment, suppose you used two electrodes separated by a distance L and a power supply with emf Vo Then you measure V for points along a straight line perpendicular to the electrodes, joining the centers of the positive and negative electrodes.
