Resistors
The above graph shows the current through a nichrome wire according to the voltage applied. If and ,) what is the resistance (in ) of the nichrome wire?
It is known that the amount of current needed to flow through a human being in order to cause them to have ventricular fibrillation (heart attack) is about 100 mA.
What is the minimum voltage (in volts) that will cause a person who has a body resistance of to have ventricular fibrillation?
If a current flows through a resistor of length m, what is the electric field strength inside the resistor?
In the circuit above, and Find the current through
If and what is the voltage of the battery?
