Question

Which of the following quantity gives a measure of how much an electrical component opposes the flow of electric current?

• A. Resistance
• B. Conductivity
• C. Conductance
• D. Potential difference

Answer 1

The correct option is A Resistance

The resistance is the property of a resistor which creates an obstruction in the flow of the current. When the voltage is applied across the conductor, the free electrons starts moving in a particular direction which constitutes the current. At a constant voltage, increasing the resistance of a substance will decrease the electric current
flowing through it.
