46

Q:

A) Resistance | B) Inductance |

C) Capacitance | D) Semi-conductor |

Answer & Explanation
Answer: C) Capacitance

Explanation: We know that, when a current pulse is applied to a capacitor, the voltage will have a waveform which rises linearly and then becomes constant towards the end of pulse. Hence, the element is a capacitor.

Q:

A) 1000 Hz | B) 2000 Hz |

C) 1025 Hz | D) 500 Hz |

Answer & Explanation
Answer: D) 500 Hz

Explanation: We know that, maximum voltage across capacitance occurs at a frequency slightly less than resonant frequency.

Here, given that resonant frequency = 550 Hz.

So, out of the given options 500 is the lowest nearest integer to 550.

Hence, 975 Hz.

Q:

A) Decrease | B) Increase |

C) Either Increase or Decrease | D) Neither Increase nor Decrease |

Answer & Explanation
Answer: B) Increase

Explanation: We know that the specific gravity of electrolyte is highest when battery is fully charged and is lowest when discharged. So, the specific gravity of the electrolyte will increase when a lead acid battery is being charged.
