Question

Define current sensitivity of a galvanometer.

Short/Brief Note
Advertisements

Solution

Current sensitivity of a galvanometer is defined as the deflection produced in the galvanometer when a unit current flows through it.

θ = `("nBA")/"k""I"`

So, for a given value of I, θ will be large if `("nBA")/"k"` is large i.e n, B and A should be large and k should be small.

The only shunt resistance available is 0.06  which is not appropriate to convert a galvanometer into an ammeter. How much resistance should be connected in series with the coil of galvanometer, so that the range of ammeter is 8 A?


Can a galvanometer as such be used for measuring the current? Explain.

The conversion of a moving coil galvanometer into a voltmeter is done by ______.


Assertion (A): On Increasing the current sensitivity of a galvanometer by increasing the number of turns may not necessarily increase its voltage sensitivity.

Reason (R): The resistance of the coil of the galvanometer increases on increasing the number of turns.

Select the most appropriate answer from the options given below:


A voltmeter of variable ranges 3 V, 15 V, 150 V is to be designed by connecting resistances R1, R2, R3 in series with a galvanometer of resistance G = 20 Ω, as shown in Fig. The galvanometer gives full pass through its coil for 1 mA current i.e. "gives full pass through it's coil for 1 mA current". Then, the resistances R1, R2 and R3 (in kilo ohms) should be, respectively:
