Your car battery is dead, and your friends are helping you start your car with cheap jumper cables. One cable carries current from theircar to your car, and a second cable returns that current to their car. As you try to start your car, a current of 80.0 A flows through thecables to your car and back, and a voltage drop of 6.00 V appears across each cable. If you replace the cheap cables with cables havinghalf their electric resistance, what voltage drop will appear across each new cable if the current doesn't change?AV=i

Electric fish generate current with biological cells called electroplaques, which are physiological emf devices. The electroplaques in the South American eel are arranged in 140 rows, each row stretching horizontally along the body and each containing 5000 electroplaques. Each electroplaque has an emf of 0.15 V and internal resistance of 0.25 . If the water surrounding the fish has resistance of 800 , how much current can the eel produce in water from near its head to near its tail?

Too much current can be a bad thing for humans too. When too much current flows through the human body, the result is electric shock or electrocution. A current of only 0.01 amperes can cause severe shock. The human body, like a piece of wire, offers resistance to the flow of electrons. The human body has a resistance of roughly 1500 ohms. Suppose you grab the two terminals of a 1.5-volt battery. Using Ohm's law (I = V /R) calculate the current that would flow through your body: Would this current cause severe shock? yes /no. Suppose your accidentally insert your fingers into a 120-volt electric outlet. Using Ohm's law calculate the current that would flow through your body: Would this current cause severe shock? yes / no. 1 This number varies greatly from person to person depending on the amount of fat (poor conductor) and muscle (good conductor) in the body. It also depends on the path of electricity through the body, presence of perspiration on the skin, and whether skin is broken…
