Consider the following situation. With the power supply off, the current limit one-half of a turn and the voltage knob completely counterclockwise, a coil is connected to it. A secondary coil is placed just in front and connected it to a galvanometer. If you gently increase the voltage of power supply, explain what you would observe in the galvanometer. Would the needle deflect? Why?
There is no change, right? Can someone explain why?
Homework Answers
Needle deflects. Simple answer is mutual induction.
When voltage knob is slightly increased the current in the circuit increases causes a change in magnetic flux. This flux is linked with secondary coil produces an induced end in the secondary coil produces current in the secondary coil. This current causes deflection in galvanometer.
