Answer to Question #283083 in Electric Circuits for Hamx

Question

Explain ohm s law?

Answer 1

Ohm law :-

the current through a conductor between two points is directly proportional to the voltage drop across the two points.

Voltage perportional to flow ofcurrent in wire

$V=IR$

R=perportional constant

Where

R=resistance

V=voltage

I=current

Ohm's for graph

Slop in tringle

$tan\theta=\frac{∆y}{∆x}$

$tan\theta=\frac{∆I}{∆V}$

$m=tan\theta=\frac{∆I}{∆V}$

$m=\frac{1}{R}$

$\frac{1}{R}=\frac{∆I}{∆V}$

Now We can written as

∆V=R∆I

This is ohm's law
