Exercise 2. An instrument used to measure current is called an ammeter. The ammeter is connected into a circuit in series in the loop in which the desired current reading is required. The resistance of an ideal ammeter is zero, and it is essential in real ammeters that the resistance of the instrument be very small compared to other resistances in the circuit. Why? R2 Ri a)-A meter to measure potential difference is called a voltmeter. To find the potential...

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...
