Web31 de dez. de 2013 · As the galvanometer's resistance (100 Ohms) is much much greater than the shunt resistance (10 mOhm), we can pretty much disregard the effect of paralleling the galvanometer's coil to our shunt. Thus, in effect the Ammeter we have created, has 10 milliOhms of resistance, which is pretty much negligible, and reads up to 1 Ampere current. WebA galvanometer coil has a resistance of \( 15 \Omega \) and it shows full deflection when \( 4 \mathrm{~mA} \) current flows through. The value of shunt resi... chugach ak weatherWebAnswer. The sensitivity of a galvanometer is defined as the constant of proportionality between the current in the coils and the angle of deflection of the arm, 𝜃 = 𝑆 𝐼. This rearranges to 𝑆 = 𝜃 𝐼.
