What shunt resistance is required to make the 1.00 mA, 20.0 Ω meter described above into an ammeter with a range of 0 to 50.0 mA?
Added by Elena F.
Step 1
We need to convert a voltmeter with a full-scale deflection of 1.00 mA and an internal resistance of 20.0 Ω into an ammeter that can measure up to 50.0 mA. To achieve this, we will use a shunt resistor in parallel with the meter. Show more…

A galvanometer has a full-scale current of $0.100 \mathrm{~mA}$ and a coil resistance of $50.0 \Omega$. This instrument is used with a shunt resistor to form an ammeter that will register full scale for a current of $60.0 \mathrm{~mA}$. Determine the resistance of the shunt resistor.
What shunt resistance should be connected in parallel with an ammeter having a resistance of 0.040 ohms so that 25% of the total current will pass through the ammeter?

A galvanometer with a full-scale sensitivity of $600 \mu \mathrm{A}$ and a coil resistance of $50 \Omega$ is to be used to build an ammeter designed to read 5.0 A at full scale. What is the required shunt resistance?
