Hey freind your answer is here
Ohm's Law:-
Ohm’s Law states that the potential difference between two points is directly proportional to the electric current.
This means; potential difference V varies as electric current.
Or, V∝IV∝I
Or, VI=RVI=R-----------(1)
Or, 1I=RV1I=RV
Or, I=VRI=VR----------(2)
Or, V=RIV=RI ----------(3)
Where R is constant for the given conductor at a given temperature and called resistance. Resistance is the property of conductor which resists the flow of electric current through it.
SI Unit of resistance is ohm. Ohm is denoted by Greek letter ‘Ω’.
1 ohm (Ω) of Resistance (R) is equal to the flow of 1 A of current through a conductor between two points having potential difference equal to 1 V.
This means 1Ω=1V1A1Ω=1V1A
From the expression of Ohm’s Law it is obvious that electric current through a resistor is inversely proportional to resistance. This means electric current will decrease with increase in resistance and vice versa.
The graph of V (potential difference) versus I (electric current) is always a straight line.
Hope it will help you

Set up the circuit depicted in the schematic diagram shown at right using the 3  resistor. Since you are probably not comfortable reading an electrical schematic, here's how:
Screw one end of the resistor to the 1.5/2 VDC terminal of the power supply.
Using one of the connecting wires, connect the other end of the resistor to the red terminal of the ammeter (labeled D.C. Amperes on the meter face).
Be sure that the switch is open.
Connect the other switch terminal to the COMMON terminal on the power supply using a wire.
Connect a wire from the red terminal of the voltmeter to the 1.5/2 VDC terminal of the power supply.
Connect a wire from the black terminal of the voltmeter to the red terminal of ammeter
Close the switch.
Carefully read the voltage across the resistor, R, and the current through the resistor, I, and record them in your data table.
Replace the 3W resistor with the 5resistor, 10 resistor, and finally the 25resistor and record the voltage and current in the circuit for each resistance
1. For each trial, calculate the expected current based on the resistance and measured voltage using Ohm's Law. Record your results in your data table, and be sure to show a sample calculation.
2. For each trial, calculate the percent of difference between the calculated and measured current in the circuit. Record your results in the data table. Show a sample calculation.
1. When the resistance in the circuit went up, what happened to the current in the circuit?
2. Do you think that your circuit follows Ohm's Law? Why or why not?

The Ohm's law states that The potential difference (voltage), V across an ideal conductor is proportional to the current through it, provided its temperature remains the same.
The constant of proportionality is called the "resistance", R.
Ohm's Law is given by:
V = I R

In this lab, you will construct a simple circuit using a single known resistance, R. Then you will use an ammeter to measure the current, I, through the resistance and a voltmeter to measure the potential difference, V, across the resistance. With this data, you can check the validity of Ohm's Law (V = IR) in the circuit.
