Consider the following Statements regarding resistance strain gauge The gauge factor is in the range of 2 to 5.The resistance changes due to change in specific resistance with strain.The resistance in

Consider the following statements :In water supply distribution network, 1. the grid-iron system requires more length of pipe lines and larger number of cut-off valves.2. the design of the grid-iron s

Which of the following pairs are correctly matched ?1. Alpha iron....non magnetic2. Beta iron....strongly magnetic3. Gamma iron....non-magnetic and capable of dissolving carbon.4. Delta iron....non-ma

Consider the following statements regarding specific energy of flow in an open channel :1. There is only one specific energy curve for a given channel.2. Alternate depths are the depths of flow at whi

In a moving iron voltmeter the coil has a resistance of 20 Ω and an inductance of 0.3 H. The swamping resistance in 2000 Ω. To ensure correct reading with dc as well as 50 Hz ac, the value of capaci

A tungsten wire used in a constant current hot wire anemometer has the following parameters : Resistance at 0° C is 10Ω, Surface area is 10-4 m2, Linear temperature coefficient of resistance of t

A resistance of 2 Ω is connected across one gap of a metre-bridge (the length of the wire is 100 cm) and an unknown resistance, greater than 2Ω, is connected across the other gap. When these resista

A resistance of 2 Ω is connected across one gap of a metre-bridge (the length of the wire is 100 cm) and an unknown resistance, greater than 2Ω, is connected across the other gap. When these resis

A resistance of 10 ohm is connected across a supply of 200V. If resistance R is now connected in parallel with a 10 ohm resistance, the current drawn from the supply gets doubled. The value of unknown

A high resistance was measured by loss of charge method. The voltmeter resistance was 1010 ohms. The calculation gave the value of unknown resistance as 0.8 x 109 ohms. The true value of resistance is
