Resistance decreases the amount of current in a circuit, because it opposes current.

Also, the relationship can be shown mathematically: Current=Voltage/Resistance

resistance is divided into the voltage, creating a smaller number which is the value for current.

Resistance decreases the flow of current in a circuit.

Step-by-step explanation:

The resistance of an electrical circuit is defined as the opposition to the flow of current in that particular circuit.

From Ohm's law, we know that current flowing through a wire I =
(V)/(R)

Here,V is the potential across the two ends of a conductor or wire, and R is the resistance of that wire.

Hence, more is the resistance, the less will be the current flow in the current.
