In most applications, a lower resistance means less power is converted to heat and lost to the surrounding environment and more of the supplied power gets to its intended destination. It also means that the wire and cable will run cooler and the power source can be smaller for a given load.
How can the range of voltmeter can be increased decreased?
The range of a given voltmeter can both be increased and decreased. has to be connected in series to the coil of the galvanometer. On the other hand, to decrease the range of the voltmeter, R has to be decreased. It can be done by putting a suitable resistance in parallel with the resistance .
Which is not an integrating instrument?
Why should a resistance be introduced in a circuit in series deliberately?
Top Answer Here the resistance is directly proportional to the Voltage and inversely proportional to the current. Thus, introducing resistance in series will decrease the current and voltage .
Which one is the integrating instrument?
Definition: An integrating instrument is an analog device which is used to measure the total energy supplied by the circuit in a given amount of time and is independent of total energy consumed. Example: The best example of integrating systems is the watt-hour meter.
Which meter is integrating type?
Definition: The integrating instrument measures the total energy supplied by the circuit in a given interval of time. It is independent of the rate at which the total energy consumed. The watt hour meter is the example of integrating instruments. This type of meter directly measures the energy in watt hour.
What is dynamometer type wattmeter?
Dynamometer type wattmeter works on very simple principle and this principle can be stated as when any current carrying conductor is placed inside a magnetic field, it experiences a mechanical force and due to this mechanical force deflection of conductor takes place.
What is meant by damping torque?
Damping torque or damping forces is the speed deviation of an electromechanical torque deviations of a machine while the angle deviation is called synchronizing torque . If the damping force is too large, then the pointer will come to rest slowly and this is called as over damping.
What is watt-hour meter?
Watt-hour meter, device that measures and records over time the electric power flowing through a circuit. Although there are several different types of watt-hour meters, each consists essentially of a small electric motor and a counter.
