Question

What does the galvanometer show while key K is held continuously pressed?

विकल्प

• Continuous deflection

• Momentary deflection in the opposite direction

• A larger deflection from faster motion

• No deflection

Answer 1

While K is held continuously pressed, the current in \[C_2\] is no longer changing. Its magnetic field and the flux through \[C_1\] remain steady, so there is no deflection.
