An RLC series circuit is fed form 100 V ac supply. Inductance is 1 H and Q = 7.5. At resonance, the voltage across inductance is
Answer: Option
Explanation:
Voltage across inductance at resonance = QV = 7.5 X 100 V.
12.
For an RLC series circuit, Z(s) will be of the form of
Answer: Option

which is similar to 
13.
In the circuit shown in the figure, steady-state was reached when the switch S was open. The switch was closed at t = 0. The initial value of the current through the capacitor 2 C is
Answer: Option
Explanation:
At steady state capacitor will be open and inductor will short circuited.
V across 2C will be = 
12v
.
14.
As temperature increases, the temperature coefficient of a metal
Answer: Option
Explanation:
It at is temperature coefficient at t°C and a0 is temperature coefficient at 0°C. 
.
15.
A wire has a resistance R ohm. If another wire of the same material and same weight has double the diameter (as compared to the first wire), the resistance of the second wire will be
Answer: Option
Explanation:
Since diameter is double, area of cross-section is four times and length is one-fourth.
