A. random motion B. circular motion C. rotational motion D. oscillatory motion Correct Answer: Option A – random motion
An ammeter of resistance 5Ω has a full-scale deflection when a current of 50 mA flows in it. The value of the resistor required to adapt it to measure a current of 5 A is?
A. 0.25Ω B. 5.00Ω C. 19.80Ω D. 0.05Ω Correct Answer: Option D = 0.05Ω Explanation R = (igrg)/I-ig = (50 x 10-3 x 5)/5-(50 x 10-3) = (0.25)/4.95 = 0.0505 = 0.05Ω
When a certain a.c supply is connected to a lamp; it lights with the same brightness as it does with a 12 V d.c battery. Then r.m.s value of the a.c supply is?
A. 12.0 V B. 3.5 V C. 17.0 V D. 8.5 Correct Answer: Option A = 12.0 V Explanation The r.m.s value of an a.c voltage/current is the value of the d.c. voltage/ current that will dissipate the same amount of energy in a given resistance as the a.c. Thus the r.m.s value...
During electrolysis; 2.0 g of a metal is deposited using a current of 0.5 A in 3 hours. The mass of the same metal which can be deposited using a current of 1.5 A in 1 hour is?
A. 1.0 g B. 0.5 g C. 3.0 g D. 2.0 g Correct Answer: Option D = 2.0 g Explanation M = Itz; z = (M)/It = (2)/0.5 x 3 x 60 x 60 = 3.703 x 10-4 gc-1 ∴ M = Itz = 1.5 x 1 x 60 x 60 x 3.703 x 10-4 = 1.99962g....Products
