OUTCOME
By the end of this lesson you will be able to apply Ohm's law to a simple model of the resistance of the human body and describe the effects of electric shock.
By applying Ohm's law to a four terminal circuit, with a known alternating current source.
"it's not the volts that kills you, it's the amps"
