Question

if cross sectional area of a conductor is decreased then what wipl happen to electric current(while having the potential constant in the circuit)​

Answer 1

Answer:

Current will decrease

Explanation:

resistance is given by

$\frac{resistivity \times length}{cross \: sectional \: area}$

Hence as cross section area decreases, resistance will increase, hence current will decrease

Answer 2

Answer:

the flow of current is slowed down that is less current will flow through that cross sectional area and the current in order to move freely will exert a high pressure on the wire
