Question

DETERMINE RESISTANCEFROM CURRENT-VOLTAGE

Suppose you apply several different voltages across a circuit and measure the current that runs through the circuit. NOTE: the current is given in milliamperes. Example, at 2 voltage, the current is 0.002A or 2mA. What is the resistance of the circuit?

Answer 1

We know that the relation is

$\boxed{V= IR}$

And

$\boxed{I =\frac{V}{R}}$

And

$\boxed{R=\frac{V}{I}}$

As given in example

V= 2

I =0.002 A

$R=\frac{V}{I}$

$R=\frac{2}{0.002}$

R(resistance )=1000 ohm
