Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)
Find the current in a conductor with resistance 2 ohm, electric field 2 units and distance 100cm.
A)
1A
B)
10A
C)
10mA
D)
100mA

Correct Answer : Option (A) :   1A


Explanation : We know that E = V/d. To get potential, V = E X d = 2 X 1 = 2 volts. From Ohm’s law, V = IR and current I = V/R = 2/2 = 1A.
