A circular coil of radius 'R' has a resistance of 40 . Figure shows two points 'P' and 'Q' on the circumference separated by a distance R 2 , which are connected to a 16 ~V battery with internal resistance of 0.5 . What is the value of current 'I' flowing through the circuit?

Options

  1. A1A
  2. B0.5A
  3. C3A
  4. D2A

Correct answer

D. 2A

Step-by-step solution

The total resistance between points P and Q . array l RPQ =(30 | 10+0.5) = 30 10 30+10 +0.5=8 array The current flowing through the circuit, array l V=I R_ P Q I= V R_ P Q array where, V is the voltage of source. I = 16 ~V 8 =2 ~A
