Batteries are not perfect. They can't deliver infinite current. As the current load on a battery gets larger, the voltage output gets smaller. We can represent this by treating batteries as if they have some small internal resistance. The circuit below shows a battery hooked up to a resistor, a voltmeter (for measuring voltages), and an ammeter (for measuring currents). When you put a measuring device on something, like a circuit, you don't want to change the circuit. So this...

In the figure a voltmeter of resistance Rv = 480 s2 and an ammeter of resistance RA = 2.03 12 are being used to measure a resistance R in a circuit that also contains Ro = 100 1 and an ideal battery of emf ε = 12.0 V. Resistance R is given by Vli, where V is the potential across R and i is the ammeter reading. The voltmeter reading is V', which is V plus the potential difference across...

A circuit you're building needs an ammeter that goes from 0 mA to a full-scale reading of 60.0 mA . Unfortunately, the only ammeter in the storeroom goes from 0μA to a full-scale reading of only 500μA. Fortunately, you've just finished a physics class, and you realize that you can make this ammeter work by putting a resistor in parallel with it, as shown in the figure (Figure 1) . You've measured that the resistance of the ammeter is 90.0...

2. (Short Circuits) An Ammeter is a device that can measure current through a circuit compo- nent. It is devised to be a device that has a VERY LOW internal resistance r. You use the device by connecting the device in series with the branch of the circuit you want to measure the current through. Suppose you accidentally connected the ammeter in parallel with a bat- tery and another resistor (with resistance R»r). Using Kirchoff's rules, show that when s...
