Question

Fill in the blanks
1)the current flows through a circuit due to the difference _________ in between two points in the conductor

2)The flow of _____________
contributes the electric current in wire

3)Current stops flowing when the potential difference between two ends of the wire becomes ____________​

Answer 1

• 1 potential difference

this is because potential difference between a conductor results in flow of current

that is flow of free electrons

• 2 free electrons

when an external force is applied, electrons held loosely starts to flow and hence produce current

• 3 zero

if potential difference is zero then their will be no current flow
