If the resistance in a circuit with constant voltage increases, the current will
A
Increase
B
Decrease
C
Its stays the same
D
Not eneough information
Explanation: 

Detailed explanation-1: -So, an increase in the voltage will increase the current as long as the resistance is held constant. Alternately, if the resistance in a circuit is increased and the voltage does not change, the current will decrease.

Detailed explanation-2: -∴ If the resistance in a circuit with constant voltage increases, the current will decreases.

Detailed explanation-3: -Ohm’s law states that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At constant voltage, current decreases as resistance increases and vice versa.

Detailed explanation-4: -Ohms law states that the current flowing in a circuit is proportional to the voltage applied to the circuit, and inversely proportional to the resistance of the circuit. In other words, for a given voltage, the current in the circuit will decrease as the resistance increases.

Detailed explanation-5: -If you hold resistance constant and change the voltage you can see mathematically that when voltage increases, current increases and when voltage decreases, current decreases. This is a direct proportion.
