Sample questions

1. 1.A wire of resistance 8 Ω is stretched to double its length. What is its new resistance?
2. 2.Refer to the table comparing an electromagnet and a permanent magnet. Why is soft iron used as the core of an electromagnet?
   • A.Soft iron has high magnetic permeability and low retentivity, allowing quick demagnetization when current is switched off.
   • B.Soft iron is cheaper and more readily available than other materials like steel.
   • C.Soft iron retains its magnetism permanently, making it ideal for long-term use.
   • D.Soft iron increases the resistance of the solenoid, reducing power consumption.
3. 3.A geyser is rated '1500 W, 250 V'. This geyser is connected to $250\mathrm{V}$ mains. Calculate: (i) the current drawn, (ii) the energy consumed in 50 hours, and (iii) the cost of energy consumed at ₹ 4.20 per kWh.
4. 4.In an electrical appliance, which part is typically connected to the earth wire for safety?
   • A.The plastic casing.
   • B.The internal wiring.
   • C.The metallic body of the appliance.
   • D.The on/off switch.
5. 5.A piece of wire is redrawn by pulling it until its length is doubled. How does the new resistance compare to the original resistance?
   • A.The new resistance is half the original resistance.
   • B.The new resistance is twice the original resistance.
   • C.The new resistance is four times the original resistance.
   • D.The new resistance is the same as the original resistance.
