46.
If absolute potential of A is - 8 V and that of B is - 16 V, VAB is equal to
Answer: Option
Explanation:
VAB = VA - VB or VAB = -8 - (-16) = 8 V.
47.
An RLC series circuit is excited by 200 V, 100 Hz supply. The current is 20 A. If R = 10 Ω, XL = 50 Ω, XC is
Answer: Option
Explanation:
= 10 Ω = 10 + y(50 - XC). Hence XC = 50 Ω
48.
For a given voltage four heating coils will give maximum heat when connected
Answer: Option
Explanation:
When in parallel each will get full voltage and hence maximum heat.
