Higher order thinking skill question on electricity

 

[Ashish kumar gupta]

As we know that electricity is the back bone of society we learn about electricity earlier now i give you 12 question after solving it we learn more about it in broader context 

1.     Calculate the no. of electrons constituting 1C of charge.

2.     How much energy is given to each coulomb of charge passing through a 6V battery?

3.     Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source? Why ?

4.     How can three resistors of resistance 2 Ohm, 3 Ohm & 6 Ohm be connected to give a total resistance of a) 4 Ohm. b) 1 Ohm

5.     Two conducting wires of the same material and of equal length and diameters are first connected in series and then parallel in a circuit across the same potential difference. What is the ratio of heat produced in series and parallel?

6.     Which uses more energy a 250 W T.V set in one hr. or 1200 W toaster in 10 minutes.

7.     Compare the power used in the 2 Ohm resistor in each of the following circuits. A) 6 V battery in series with 1 Ohm and 2 Ohm resistors. B) 4 V battery in series with a 12 Ohm and 2 Ohm resistor.

8.     Two wires A and B have equal length and equal resistance, which one is thicker?

9.     100 J of heat are produced in each second in a 4 Ohm resistance. Find the potential difference across the resistance?

10.  An alpha particle projected towards west is deflected towards north by magnetic field. Find the direction of magnetic field?

11.  An electric oven of 2 Kilowatt power rating is operated in a domestic electric circuit 220V  that has a current rating of 5A. What result do you expect ? Explain

12.  Why does a current carrying solenoid coil when suspended freely rests along north south direction?
