Question

Here is the graph given below for the variation of current with time. Find the magnitude of virtual

current. I (in ampere)

(A) 1 ampere

(B) 3.5 ampere

(C) 5 ampere

(D) None of these​

Answer 1

Answer:

5 ampere

Explanation:

This is correct answer because last

Answer 2

Virtual current :

Explanation:

• Virtual current is the current which generates exactly the same heat in the resistance as a steady current of 1 ampere produces in the same time frame.

• The virtual current is given by

         V = IR

          where

         V = voltage across the circuit

         I = current flowing the circuit

         R = resistance in the circuit

• The current in the circuit having voltage V = 1V & resistance R = 1 ohm is given by

         1 = I ( 1 )

         I = 1 A

Option a is correct.
