A galvanometer is an instrument that can detect the presence of a current in a circuit. The pointer remains at zero for zero current flowing through it. It can deflect to the left or to the right of zero mark depending on direction of current.
1. If a coil wrapped with wire is connected with galvanometer and a magnet is moved near it, what will you observe?
a. There will be momentary deflection in galvanometer
b. The pointer remains at zero
c. There are rapid defections in the galvanometer
d. None of the above
2. What does the deflection in galvanometer mean when a current carrying coil is connected to it while you move a magnet near it?
a. There is frictional force generated in the coil.
b. There is nuclear force generated in the coil.
c. There is electric field set up in the coil
d. Both B and C
3. Galvanometer detects the amount of force in a circuit. True or false?
a. TRUE
b. FALSE
4. Its deflection depends upon the direction of current. True or false?
a. TRUE
b. FALSE
5. If a coil wrapped with wire is connected with galvanometer and a magnet is stationary near it, what will you observe?
a. There will be momentary deflection in galvanometer
b. The pointer remains at zero
c. There are rapid deflections in the galvanometer
d. None of the above
