Question

Which of the following is the tendency for a material to oppose the flow of electrons and change electrical energy into thermal energy?

A. resistance

B. volts

C. Ohms

D> electric current

Answer 1

A. Resistance, is the tendency for a material to oppose the flow of electrons, the reason it isn't electric current, is because that is the general flow of electric charges in one direction.

Answer 2

The correct answer is option A.

Step-by-step explanation:

Resistance :It is a measure of the opposition against the flow of electric current in an electric circuit.It is also defined as ratio of voltage applied to the current. It is measured in Ohms.

`Resistance(R)=(Voltage(V))/(Current(I))`

Voltage is defined as work done to move an unit charge from one point to another against the electric field.it is measured in Volts.

Current is defined as flow of electrical charges through an electrical circuit.It is measured in ampere.
