GENERAL KNOWLEDGE

Detailed explanation-1: -Assuming that the voltage remains the same, what would happen to the current if the resistance within a circuit is increased? This is like plugging more globes into a circuit, as the resistance increases, the current decreases. In this case, there is a inverse relationship between the two variables.

Detailed explanation-2: -Alternately, if the resistance in a circuit is increased and the voltage does not change, the current will decrease.

Detailed explanation-3: -If it is voltage source, current in the circuit will reduce with net increase in resistance. Correspondingly voltage across a given resistance will reduce. However if it is a current source, it has to keep the current constant, and so voltage across resistance will go up with any increase in resistance value.

Detailed explanation-4: -Current will decrease when voltage decrease, and will do so by a constant proportion.

Detailed explanation-5: -The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.
