The force per meter between the two wires of a jumper cable being used to start a stalled car is 0.025 N/m. What is the current in the wires, given they are separated by 2.00 cm?

Taking R = 1.50 kΩ and ε = 150 V in the figure shown below, determine the magnitude and direction of the current in the horizontal wire between a and e. 17.5 mA, from e to a19.9 mA, from a to e    18.0 mA, from e to a18.9 mA, from a to e18.0 mA, from a to e19.9 mA, from e to a

When the switch is open, the potential difference across the terminals of a battery is 20 0.0V. When a current of 2.0A flows, the potential difference across the battery drop to 16V. If this battery consists of two identical cells in series, what is the electromotive force of each cell? 8.0V 10.0V 16.0V 20.0V

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.
