Question

26. the adjoining graph is a V-I graph. calculate resistance from the graph​

Answer 1

Explanation:

Ohm's law is: The current flowing through a conductor is directly proportional to the voltage applied across the conductor

means I∝V or I=

R

V

.....eq.( 1 )

from equation 1 we can see , the slope of I−V graph is 1/R which is a constant. graphically it can be shown as shown in figure of option B. Hence option B is correct.
