Voltage and current tend to be proportional. It is better to understand that voltage is the force that causes the current, which is the electromotive force. Energy is pushed like pressure pushes water in pipes. The voltage-current will flow. The circuit resists the flow. The more the circuit resists the flow, the less current will flow.
There is an inverse correlation between current and resistance. The current that flows is the result of both the voltage and the resistance of the circuit. The current is proportional to voltage and intensely proportional to current. Typically, in a circuit, the voltage will be reasonably constant and changing the resistances will change the current.
