1. Cells are connected in series in order to increase the
- current capacity
- life of the cells
- voltage rating
- terminal voltage
2. Cells are connected in parallel in order to increase
- life of the cells
- efficiency
- current capacity
- voltage rating
3. When two cells are connected in parallel , it should ensure that have
- identical internal resistances
- equal emfs
- same ampere hour capacity
4.The capacity of a battery is expressed in
- amperes
- amperes-hour
- watts
- watt-hour
5. A series resonant circuit implies
- zero pf and maximum current
- unity pf and maximum current
- unity pf and minimum current
- zero pf and minimum current
6. which one is classified as integrating instrument?
- D’arsonval galvanometer
- Ampere-hour meter
- ohm-meter
- ammeter
7. Which of the following types of instrument is an integrating instrument?
- power factor meter
- energy meter
- watt meter
- frequency meter
8. Voltmeter should be of very high resistance so that
- its range is high
- its accuracy is high
- it may draw current minimum possible
- its sensitivity is high
9. If a voltmeter is connected like a ammeter in series with a load
- the measurement reading will be too high
- almost no current will flow in the circuit
- the meter will burn out
- an inadmissably high current will flow
10. A multirange instrument (ammeter or voltmeter) has
- multiple shunt or series resistances inside the meter
- variable coil turns
- multi -coil arrangement
- any of the above
