Representation of Ohm`s Law and Power Consumption in a Circuit

In this kit we are changing the value of resistance in a loop and oversving the change in current in the given loop. As per ohms law , current flowing between any two points is directly proportional to the voltage difference between them and inversly proportional to the resistance between them. From the given circuit diagram we can understand the concept very easily. Here we are changing the loop resistance from R1 to R4, clearly as resistance increases the current will decrease and hence the intensity of ligh (LED) will also decrease.
