Ohm's law, discovered by German physicist Georg Simon Ohm in 1827, states that the current through a conductor is directly proportional to the voltage applied, provided the physical conditions of the conductor remain unchanged. It explains the relationship between voltage, current, and resistance, and is used by electricians, automotive technicians, and stereo installers. The law is represented by the equation V=I*R, where V is voltage, I is current, and R is resistance.

1. V=I*R

2. OHM’S LAW
The law was given by German
physicist GEORG SIMON OHM in
1827 . His lifespan was from 1787 to
1854 . He was also known as Mozart
of electricity

3. OHM’S LAW
This law states that when physical
conditions remain’s unchanged then
current flowing in the conductor is
directly proportional to potential
difference applied across the conductor

4. USES OF OHM’s LAW
Ohm’s Law explains the relationship between
voltage , current and resistance
Used by electricians, automotive technicians,
stereo installers

5. VOLTAGE is the difference in charge between two
points . It is also known as Electric Potential
Difference . It’s S.I. unit is Volt . It’s symbol of
representation is V .
VOLTAGE
2 volt
battery

6. CURRENT
CURRENT is the rate at which charge is
flowing .
It’s symbol of representation is I .
It’s S.I. unit is ampere .
Flowing
current

7. Resistance is a material’s tendency to resist
the flow of charge .
It is measured in ohm .
It’s symbol of representation is R .
RESISTANCE
Resistor

8. .
Assuming the resistance does not change:
As voltage increases, current increases.
As voltage decreases, current decreases.
Assuming the voltage does not change:
As resistance increases, current decreases.
As resistance decreases, current increases.
