6.
A resistance coil has self inductance L, resistance R and capacitance C. The impedance across the coil is
Answer: Option
Explanation:
The coil has R and L in series and C in parallel.
7.
In figure, the current iL at t = ∞ is
I
0
Answer: Option
Explanation:
At t = ∞, inductance behaves as short-circuit.
8.
When a lead acid cell is in fully charged condition the positive and negative plates are similar.
Answer: Option
Explanation:
They are similar in discharged condition.
9.
Two capacitors of 1 μF and 2 μF capacitance are connected in parallel across a 30 V dc battery. After the capacitors have been charged, the charges across the two capacitors will be
Answer: Option
Explanation:
Q1 = 1 x 10-6 x 30 = 30 μC, Q2 = 2 x 10-6 x 30 = 60 μC.
