Question

$A,B$ and $C$ are the three coils of conductor having different number of turns, wound around a soft iron ring as shown in the figure. Ends of coils $B$ and $C$ are connected to the galvanometers. The observation that can be made when ends of coil $A$ are connected to an A.C. source is

• A. Same electric current is induced in $B$ and $C$
• B. No electric current is induced in $B$ and $C$
• C. Induced electric current is more in $B$ than in $C$
• D. Induced electric current is less in $B$ than in $C$

Answer 1

The correct option is C Induced electric current is more in $B$ than in $C$

When the end of coil A is connected to an A.C source the induced electric current will be more in $B$ than in $C$ as the number of turns in the coil is more in $B$ than in $C$.
