Consider the following statements and select the correct answer f
Assertion [A]: Voltage, Current and Resistance are the three basic parameters of electricity.
Reason [R]: Resistance is responsible for controlling the amount of current flow.
A. Both [A] and [R] are true and [R] is the correct explanation of [A]
B. Both [A] and [R] are true and [R] is not the correct explanation of [A]
C. [A] is true but [R] is false
D. Both [A] and [R] are false
Please scroll down to see the correct answer and solution guide.
Right Answer is: B
SOLUTION
Electricity can be defined as the flow of free electrons in a conductor. There are three basic parameters of electricity voltage (Volt), current (Ampere) and the resistance (Ohm). Voltage is the Electromagnetic force required for the electric charge to flow in a conductor while the current defines the direction of flow, and the resistance controls the amount of flow by providing resistance. Greater the resistance lesser is the flow.
According to Ohm’s Law:
V= IR
Where,
V = Voltage
I = Current
R = Resistance
Thus, both [A] and [R] are true, but [R] is not the correct explanation of [A]. So, option B is the correct answer.
