An 18-gauge copper wire diameter 102 mm carries a current


Solve the all parts of given problem:

Problem: An 18-gauge copper wire (diameter 1.02 mm) carries a current with a current density of 1.50 x 106 A/m2. Copper has 8.5 x 1028 free electrons per cubic meter.

Part A: Calculate the current in the wire?

Part B: Calculate the drift velocity of electrons in the wire?

I need help to find the drift velocity of electrons in the wire and express your answers using two significant figures.
