By modeling the arm and the chest to be a cylindrical tube with a total length 2.0 m, cross-sectional area 10 cm^2, and resistivity 1.5 ohm*m, you can calculate the current in amperes through the person when a potential difference of 110 V is applied across the two hands. Assume that the current flows only through the modeled cylindrical tube. What is the current flow through the body?
vincentchan said:the cross section area is in cm... and the rest of your problem is in SI ...
vincentchan said:and do you still got 367... if you do... change battery for your calculator, or do the calculation by hand...
vincentchan said:it is 3.67
vincentchan said:maybe you have to enter 3.67A... since the computer said check your unit
vincentchan said:10 cm^2 = .o1 m^2...did you do the convertion correctly?
Electric current is the flow of electric charge, typically in the form of electrons, through a conductor. It is measured in units of amperes (A).
The strength of an electric current is affected by three main factors: the voltage difference between two points, the resistance of the conductor, and the type of material the conductor is made of.
The electric current in a circuit can be calculated using Ohm's Law, which states that current (I) equals the voltage (V) divided by the resistance (R). So, I = V/R.
There could be several reasons why your electric current is not working. Some common reasons include a faulty circuit, a loose connection, or a blown fuse. It is important to troubleshoot and identify the specific issue in order to fix it.
To increase the electric current in a circuit, you can either increase the voltage or decrease the resistance. However, it is important to note that increasing the current too much can cause overheating and damage to the circuit. It is important to carefully balance these factors in order to maintain a safe and functioning circuit.
