Final answer:
If the current is decreased in a circuit, the amount of current flowing through the circuit will decrease.
Step-by-step explanation:
If the current is decreased in a circuit, the amount of current flowing through the circuit will decrease. This is because current is the flow of electric charge, and decreasing the current means reducing the number of charges passing through the circuit per second. For example, if a circuit initially has a current of 2 Amperes and the current is decreased, the new current might be 1 Ampere.
One way to understand this is through Ohm's Law, which states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance. If the voltage and resistance remain constant and the current is decreased, it means there is a decrease in the number of charges passing through the circuit per second.
