What is the current I in the given circuit (Fig. )?

#### Solution

In given circuit, two 2 ohm resistors in series are connected in parallel with another 2 ohm resistor;
Therefore equivalent resistance of the circuit,

R = [(2 + 2-1 + (2)-1]-1

R = (1/4 + 1/2 = 3/4)-1

R = 4/3

I = "V"/"R" = 3/(4//3) = 9/4 A = 225A

Concept: Electrical Energy and Power
Is there an error in this question or solution?
