Which is a scalar quantity?

• Flux

• Electric field

• Current

• Magnetic field

Relation between Capacitance & Area of plates in a Parallel Plate Capacitor is_________​

Why is voltmeter called HIGH RESISTANCE GALVANOMETER?

Choose the incorrect option about shunt

• It is actually A High Resistance

• Resistance of low value is connected in parallel with galvanometer

• Used to convert galvanometer into ammeter

• Increases the range of ammeter

Ideal voltmeter has

• Infinite resistance

• 0 resistance

• Depends upon circuit elements

Choose correct option about Ammeter

• It is placed in parallel combination within circuit

• We can only decrease the range of ammeter by connecting resistance in parallel with it

• We can only increase the range of ammeter by connecting resistance in parallel with it

• Both b & c

The magnitude of induced emf in a circuit is given by

• Faraday 1 law

• Lenz law

• Faraday 2 nd law

Current induced in conductor when magnetic flux in them changes is called_______

Current can be induced in

• Only conducting coils

• Conducting sheets

• Conducting blocks

• All of the above

__________ is not an application of Eddy currents

• Speedo meters

• Electric brakes

• Induction furnace

• Inductothermy

• Charging a mobile phone
