Question 5

To measure a.c. as well as d.c. power, we use

Question 6

A 230 V single phase energy meter has a constant load current of 4 A passing through if for 5 hours at unity power factor. If the meter makes 1104 revolutions during this period, the meter constant is

Question 7

A moving coil galvanometer with a scale divided into equal divisions has a current sensitivity of 10 divisions per mA and voltage sensitivity of 50 divisions per mV. To convert it into an ammeter of range 5 A. the necessary shunt resistance required is
