Two conducting wires of same material, equal length and equal diameter are first connected in series and then in parallel. Compare the equivalent resistance in two cases.  ​

Answer»

Explanation:Since the two wires have same material, length and diameter, they have the same RESISTANCE. Let the resistance of each wire be R.Let applied POTENTIAL difference be V.R series =R 1+R2​ =R+R=2RP series=V²/R =V²/(2R)..........(i)1/R parallel= 1/R1+/1R2​R parallel=R/2P parallel=V²/R parallel =2V²/R............(II)DIVIDING (ii) from (i),P parallel/P series=1/4HOPE THIS HELPS YOU

Two electric bulb P and Q have their resistance are in 1:2.they are connected in series across a battery. Find the power dissipation in these bulb ​

Answer» HAT, the ratio of the resistance of two electric bulbs P and Q are 1:2. Both of them (bulbs) are connected in a series across a battery. MEANS current is the same in both the bulbs.The resistance of bulb P, resistance is 1Ω and for bulb Q, resistance is 2Ω.Now, P' = VI { P' = V (Q/t) = VI }Here, Power is denoted by P'.Also, from Ohm's LawV = IRSo, P' = I²R{ P' = Power, I = Current and R = Resistance }For bulb P: (Power = P1)→ P1 = I²(1)For bulb Q: (Power = P2)→ P2 = I²(2)So, → P1/P2 = (I² × 1)/(I² × 2)→ P1/P2 = 1/2The power dissipation in these bulbs is the same or equal to the ratio of resistance OFFERED i.e. 1:2.

Answer»

Car moves with 40 km/hr for half DISTANCE and 60km/hr with ANOTHER half distance. We need to find out the average speed of the car.First of all, we need to remember the definition of average speed : It's the ratio of total distance to the total time TAKEN to cover that distance.Calculation:Cancelling the similar term :So FINAL answer is:Average speed is 48 km/hr

1.Differentiate between conductors and ins2.Discuss the effect of heat on substances.​

Answer»

Difference between conductors and insulaters The most common difference between the two is that while conductors allow free FLOW of electrons from one atom to another, insulators restrict free flow of electrons. Conductors allow electrical energy to pass through them, whereas insulators do not allow electrical energy to pass through them.Effect of heat on substance. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The MOTION and spacing of the particles DETERMINES the STATE of matter of the substance. The end RESULT of increased molecular motion is that the object expands and takes up more space.
