Expert Answer
Electric current - The rate flow of charge in a conductor is called electric current.
V= IR
V - voltage/potential difference
I -Current
R -Resistance
By keeping resistance in the conductor constant, the value of current can be increased by increasing the value of potential difference.
While value of current can be decreased by decreasing the value of potential difference.
