## Class 10 Physics (India)

### Unit 3: Lesson 3

Circuits, Ohm's law & resistance

# Solved example: (Ohm's law graph)

Let's see how to compare the resistance of materials from V-I graphs. Created by Mahesh Shenoy.

• He says we should take current or voltage as a same value, and either we choose current or voltage, we get the same value. At , he says that Material 1 has higher resistance because it has higher voltage, but if we take voltage as same, we get the solution as Material 2 because it has higher current. What is the correct solution??
• Hey there,
I'm not gonna give you the answer right away, just a hint,
`in a fraction p/q, as q(the denominator) increases the value decreases`
so,what would happen if I increases?
I is the denominator
Hope this helps (though I didn't tell you the answer ;))
