When a inductive coil connected to a 200 V, 50Hz ac supply with 10A current flowing through it dissipates 1000 watts then which of the following will have least value in ohms-a.) Resistance b.) Reactance c.) Impedance d.) None 2 Oscillator crystal are made of – a.) Silicon b.) Germanium c.) Quartz d.) None 3. For small size, high frequency coils, the most common core material is- a. )Air b. )Ferritec.) Powdered ion d.) Steel 1. 4. If we have a parallel plate capacitor of plate area 'A' and plate separatoin t and having a capacity C and a metallic plate r of area A and of negligible thickness is introduced in the capacitor at a distance from either of the two plates as shown in the given figure then the capacity of the capacitor will become – a.) b.)C c.)2C d.)4C
