Explanation:
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.
Answer:
A voltage always exists, it may either be positive, negative or zero between two points, but the flow of current depends only on the voltage gradient between them.
Explanation:
Voltage can be either positive or negative. The direction of current flow does not affect what the current does within the circuit.
