Derive ohm's law and please explain it clearly i am so confused in it
Answers
In 1828, George Simon Ohm, a German physicist, derived a relationship between electric current and potential difference. This relationship is known as Ohm’s law.
What is Ohm’s Law?
Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as,
Potential difference ∝ Current
V ∝ I
V = IR
Where,
V is Voltage in volts (V)
R is Resistance in ohm (Ω)
I is Current in Ampere (A)
The main applications of Ohm’s law are:
1 .To determine the voltage, resistance or current of an electric circuit.
2.Ohm’s law is used to maintain the desired voltage drop across the electronic components.
3.Ohm’s law is also used in dc ammeter and other dc shunts to divert the current.
(unknown third parameter can be easily calculated as follows:
To find Voltage(V),
V = IR
To find Current(I),
I=VR
To find Resistance(R),
R=VI)
