Physics Question on Current electricity

The current II drawn from the 55 volt source will be:

A

0.33 A0.33\, A

B

0.5 A0.5\, A

C

0.67 A0.67\, A

D

0.17 A0.17\, A

Answer

0.5 A0.5\, A

Explanation

Solution

The given circuit can be redrawn as which is a balanced Wheatstone?s bridge and hence, no current flows in the centre resistor, so equivalent circuit would be as shown below. So, I=VR=5/10=0.5 AI=\frac{V}{R}=5/10 = 0.5\,A
