When a potential difference of 0.5 V is supplied to the patient's arm and a 1ma current is measured, the resistance of fat is 2000 Ω, which is three times the resistance of muscle.
What is resistance ?
The force that opposes the movement of charged particles (electrons) through a medium, or current, is referred to as resistance. It is expressed in Ohms, a unit named for Georg Ohm, who made significant contributions to our understanding of the connection between current and resistance.
Determination of fat resistance.
Since either fat or muscle might be a path for current flowing down the arm, we can overcome this issue by seeing fat and muscle as parallel resistors. We may construct an equation for the total resistance of the arm if we define RF as the resistance of fat and RM as the resistance of muscle:
[tex]RT = \frac{1}{\frac{1}{RF} + \frac{1}{RM} } = RF * \frac{RM}{RF + RM}[/tex]
Furthermore, given that we are aware that fat has three times the resistance of muscle:
[tex]RT = RF * \frac{\frac{1}{3} * RF }{RF + \frac{1}{3} * RF } = \frac{RF}{4}[/tex]
After that, we can calculate the total resistance using Ohm's Law:
V = I × RT
[tex]RT = \frac{V}{I} = \frac{0.5V}{0.001A}[/tex]
RT = 500Ω [tex]= \frac{RF}{4}[/tex]
When we solve for fat resistance, we obtain:
RF = 4 × 500Ω = 2000Ω
Therefore, the resistance of fat is 2000 Ω.
