Question

What is the tendency of a material to oppose the flow of charge?

Answer 1

The answer is B. resistance

Answer 2

Answer: Resistance

Explanation:

The tendency of a material to oppose flow of charges through it is known as resistance. It is an opposing force that acts against the electric current. It depends on the resistivity of the material, its length and diameter. It also depends on the temperature. With increase in temperature, resistance increases.

$R = \frac{\rho l}{A}$

It is measured in Ohms (Ω)

At constant voltage,

$I \propto \frac{1}{R}$

Thus, more resistance leads to low current value.
