A moving coil meter is a very commonly used form of analogue voltmeter because of its sensitivity, accuracy, and linear scale, although it only responds to d.c. signals. As shown schematically in Figure 7.3, it consists of a rectangular coil wound round a soft iron core that is suspended in the field of a permanent magnet. The signal being.

Answer: 3. Explanation: The soft iron core increases the strength of the magnetic field inside a transformer. The main purpose of using an iron core in a transformer because iron is a magnetic material and it is easily available everywhere.

Solution Verified by Toppr Correct option is D) The core of a transformer is made of soft iron because it has high permeability so it provides complete linkage of magnetic flux of the primary coil to the secondary coil. Therefore ithas high coercivity and low retentivity. Solve any question of Alternating Current with:- Patterns of problems >

A) the surface of ice is smooth B) ice is cold C) the pressure on the ice due to skate melts the ice by lowering its melting point forming a thin film of water D) the pressure on the ice due to skate raises its melting point

Aqueous ammonia reacts with Fe ( III) ions to produce red-brown Fe ( OH) 3: (2) Fe 3 + ( aq) + 3 NH 3 ( aq) + 3 H 2 O ( l) ↽ − − ⇀ Fe ( OH) 3 ( s) + 3 NH 4 + ( aq) Both precipitates are insoluble in excess aqueous ammonia. Iron (II) hydroxide quickly oxidizes to Fe ( OH) 3 in the presence of air or other oxidizing agents.

There are several reasons why students skip class. Some are unavoidable, but others are, particularly those brought on by failing to take preventative or early action. Accidents, unfavourable weather, and illness are examples of unavoidable causes that are often beyond human control.
