Question

study the VI graph for a resistor as shown in the figure and prepare a table showing the values of I (in
amperes) corresponding to four different values of V (in volts). Find the value of current for V = 10 volts.
How can we determine the resistance of the resistor from this graph?
​

Answer 1

the answer is in the above attachment.

Answer 2

Answer:

Using Ohm's Law and by studying the graph, we get that the value of current for 10 Volts is 5A and the value of resistance of the resistor from the graph is 2 Ω

Explanation:

A V-I graph has been given for a resistor.

Four Values have been given to us through the graph,

So, we evaluate each value to calculate the value of resistance.

For Voltage (V) = 2 V , Current (I) = 1 A

And we know that V = IR

So, R = V/I = 2/1 = 2 Ω

Similarly, For Voltage (V) = 4 V , Current (I) = 2 A

So, R = V/I = 4/2= 2 Ω

Thus, For all the given four values, the value of the resistance is the same, that is, 2 Ω

Now, we evaluate the value of current for 10 V

Again, using Ohm's Law, we have :

V = IR

I = V/R

I = 10/2 = 5 A

Thus, for Voltage 10 V, the value of the current is 5 A.
