A voltmeter reads 8V at full-scale deflection and is graded according to its resistance per volt at full-scale deflection as 5000 ohms/volt. How will you convert it into a voltmeter that reads 20V at full-scale deflection? Will it still be graded as 5000 ohms / volt.? Will you prefer this voltmeter to one that is graded ats 2000 ohms /volt? PLEASE ANSWER IT EARLIEST

Justify E=J ROW row is restivity J=sigma E sigma is conductivity. In current density current are perpendicular to area, justify. Dimensions of drift velocity. Dimensions of mobility.mobility is always positive. why temperature are directly proportional to resistance. Why ammeter are connected in series and voltmeter connected in parallel. An electric bulb is rated 220V and 100W, when it is opraoperon 110V ,why the resistance of the bulb remain constant in both voltage case . potentiometer function is where no current flow the device used to measure potential deference but when no current flow how potential deference is possible.

You are given a resistance wire AB connected with a cell and a key S. You are required to measure the current in the wire AB and potential difference across it. Name the instruments that you would use and draw a labelled diagram to show how are they connected. Also mark the direction of current in each component
