Which statement correctly describes the relationship between current, voltage, and resistance? if we

a: decrease the resistance, and do not change the voltage, the current will decrease.

b: decrease the voltage, and do not change the resistance, the current will also decrease.

c: increase the resistance, and do not change the current, the voltage will remain the same.

d: increase the current, and increase the resistance, the voltage will decrease.

Option (b) is the correct answer.

Explanation:

According to ohm's law, the relationship between voltage, resistance, and current is that current passing through a conductor is directly proportional to the voltage over resistance.

Mathematically,           I =

From this relationship we can see that when we decrease the voltage, and do not change the resistance, the current will also decrease. As current is directly proportional to voltage and inversely proportional to resistance.
