In this question, we have to first find out the relationship between current and voltage for a resistor.
00:07
The relationship between current and voltage of the resistor is directly proportional because we know from ohm's law that v which is the voltage is equals to i, the current multiplied by resistance r.
00:25
The actual form of ohm's law is nothing but v directly proportional to i and here r is just the constant of proportionality to convert this form into an equation.
00:42
So the ohm's law implies that the voltage across the resistor is directly proportional to the current passing through it.
00:50
As the current increases, the voltage difference across the resistor also increases.
00:55
This relationship forms a linear graph where voltage is on the y -axis and current is on the x -axis.
01:10
This will form a linear graph.
01:13
So from ohm's law, we know that r is equals to del v by del i, that is change in voltage divided by change in current...
