A galvanometer of resistance \(50\,\Omega\) gives full-scale deflection when a current of \(2\,\text{mA}\) passes through it. The value of shunt resistance required to convert it into an ammeter of range \(2\,\text{A}\) is

A galvanometer of resistance \(50\,\Omega\) gives full-scale deflection when a current of \(2\,\text{mA}\) passes through it. The value of shunt resistance required to convert it into an ammeter of range \(2\,\text{A}\) is

In a moving coil galvanometer, the magnetic field is made radial so that the:

To convert a galvanometer into an ammeter, we use:

A steady current flow through a long straight wire of radius ' $a$ '. The current is uniformly distributed across its cross section. The ratio of the magnetic fields due to the wire at distance $\frac{a}{4}$ and $3a$ respectively from the axis of the wire is

To protect galvanometer from possible damages due to large current, which of the following should be connected to its coil:

A galvanometer having a resistance of 8Ω is shunted by a wire of resistance 2Ω. If the current is 1 A, the part of it passing through the shunt will be:
