PROBLEM 2: An electric circuit has a battery with an EMF of 1.50 V. Its positive terminal is connected to its negative terminal by a copper wire in a circular loop having a radius of 0.500 m. Solve for the drift velocity in the wire if there is one free electron per copper atom. Detailed assumptions: - The size of the cell is negligible compared to the length of the circuit. - Copper resistivity: p = 1.80x10-8n-m - Copper density: D = 8.96x 10° kg-m-3 - Copper relative atomic mass: m, = 63.5 g/mol

PROBLEM 2:
An electric circuit has a battery with an EMF of 1.50 V. Its positive terminal is connected to its
negative terminal by a copper wire in a circular loop having a radius of 0.500 m. Solve for the
drift velocity in the wire if there is one free electron per copper atom.
Detailed assumptions:
- The size of the cell is negligible compared to the length of the circuit.
- Copper resistivity: p = 1.80x10-8n-m
- Copper density: D = 8.96x 10° kg-m-3
- Copper relative atomic mass: m, = 63.5 g/mol
