paragraph aod the related studied concepts.:-
In 1827, a German physicist Georg Simon Ohm (1787-1854) found the relationship between
the current I flowing in a metallic wire and the potential difference across its terminal. The
potential difference. V across the ends of a given metallic wire in electric circuit is directly
proportional to the current flowing through it. provided temperature remains the same. This is called Ohm's law.
V.
Val V = IR
(a) What is resistance?
(6) Show graph between V vs I
(c) Calculate voltage when current is 0.6A, and resistance is 1012
(d) How does resistance depend on temperature?
