Question

In the circuit shown the current in 4W, 8W resistances are –

• A. 2.5 A, 0A
• B. 5A, 0A
• C. 2.5A, $\frac { 40 } { 3 }$ A
• D. 5A, $\frac { 80 } { 3 }$A

Answer 1

Answer: (A)

2.5 A, 0A

Answer 2

4 × x – 10 = 0 (Kirchoff's law)

x = $\frac { 10 } { 4 }$ = 2.5 A

$\left( 10 + \frac { 2 } { 3 } \right)$ I – 10 + 10 = 0 Ž I = 0
