Question

A resistor is connected to a battery by which temperature in the wire increases which value does not change. A)drift speed of electrons B)electrical resistivity C)Density of electrons D)resistance​

Answer 1

Answer:

c

Explanation:

if you like please follow me back.the resistance will change because a resistor is added.speed of electrons will decrease because of increase in resistance. resistivity increases.but density of electrons will not change .so the correct answer is c)density of electrons.

Answer 2

Answer:

A wire 50.0 m long and 2.00 mm in diameter is connected to a source with a ... wire? (d) What is the drift speed of the conduction electrons? ... Assume its resistance does not change.
