V proportional to I [only at Constant temp.]
V = IR [where R is constant of proportionality]
Graph of V and I is a straight line
Ohm's law :-
according to Ohm's law
if the physical condition for example temperature remain unchanged the potential difference applied across the end of conductor is directly proportional to current flowing through it.
V directly proportional to I
means voltage directly proportional to current.
therefore, V = iR .

hope it helps
Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance.
Volume of conductor = A.l
Total number of free electrons = A.l .n
Total free charge, Q = A.l .n.e
Time taken by a free electron to cross the conductor of length l ,
Current I = Q/t = (A.l .n.e)/ (l/v) = n.e.A.v —————(1)
v = μ. E and
μ = e.τ/m. & E = V/l.
v = e.V.τ/(m.l);
I = n.e.A.v
V/I = m.l/(n.A.τ. e^2) = R(Resistance)
V = IR
Ohm's law state that potential difference is directly proportional to current passing through conductor ___
There graph is always constant __
where R is constant of proportionality and is called resistance ____ ✨✨✨
Plzzz Refer to attachment ____ ☺️☺️
Ohm's Law and Resistance. Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.
Ohm's Law Equation : V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
Electric power is the rate at which energy is transferred to or from a part of an electric circuit. A battery can deliver energy, or a circuit element like a resistor can release energy as heat. For any circuit element, the power is equal to the voltage difference across the element multiplied by the current. By Ohm's Law, V = IR, and so there are additional forms of the electric power formula for resistors. Power is measured in units of Watts (W), where a Watt is equal to a Joule per second (1 W = 1 J/s).
electric power = voltage difference x current
P = VI
P = electric power (W)
V = voltage difference (V = J/C)
I = electric current (A = C/s)
R = resistance (Ω = V/A)
Ohm's Law :-
It states that , on a constant temperature , the current I , flowing through the electric circuit , is directly proportional to the potential difference V , across its ends.
V ∝ I
I ∝ V
V/ I = R , constant of proportionality
R = Resistance [ opposes flow of current ]
V = IR
R = V/I
I = V / R
Ohm's law states that Current through a conductor is directly proportional to voltage difference across it. ... The circuit diagram to verify ohm's law is drawn below. Voltmeter across a resistor is connected in parallel. Ammeter to measure current in the circuit is attached in series. A variable resistor is connected.
Ohms Law and Power
1. [ V = I x R ] V (volts) = I (amps) x R (Ω)
2. [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
3. [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
4. It is sometimes easier to remember this Ohms law relationship by using pictures.
o i see then answering
