What is the sensitivity of the galvanometer (that is, what current gives a full-scale deflection) inside a voltmeter that has aresistance on itsscale?
(a) Calculate the capacitance needed to get an \(RC\)time constant of \(1.00 \times {10^3}\;s\) with a \(0.100 - \Omega \) resistor. (b) What is unreasonable about this result?(c) Which assumptions are responsible?
When an unknown resistanceis placed in a Wheatstone bridge, it is possible to balance the bridge by adjusting to be . What is if?
If a potentiometer is used to measure cell on the order of a few volts, why is it most accurate for the standard to be the same order of magnitude and the resistances to be in the range of a few ?
