Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

When you increase voltage what happens to current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

Does increase in voltage increase current?

Current is directly proportional to the voltage. A fourfold increase in the voltage would cause a fourfold increase in the current.
