True or False?
1. Current density is a measure of the amount of current flowing through a volume.
2. The conventional direction of current is the hypotheticaldirection of movement of positive charges through the wires of anelectric circuit.
3. Through a certain cross-sectional area of a wire, one coulomb ofelectrons pass each second. In this case, the current through thewire is equal to one ampere.
4. A 10-ohm resistor has a constant current. If 1200 C of chargeflow through it in 4 minutes, the value of the current is 5A.
5. Current density is a measure of the amount of current through across-sectional area.
