Question

The figure shows in apart of an electric circuit, then the current I is

• A. $1A$
• B. $3A$
• C. $2A$
• D. $4A$

Answer 1

Answer: (B)

$3A$

According to the Kirchhoff's first law, amount of current entering is equal to amount of current leaving.

From the circuit,

$I+6+1=5+3+2$

$I+7=10$

$I=3A$
