You have a 10 ohm resistor connected in series with an ammeter. The voltage applied to the whole circuit is 1.2 volts. At the same time you have a voltmeter connected across the 10 ohm resistor and voltmeter reads 0.9 volts. The circuit draws a total of 0.5 amps. Can you determine resistance of the ammeter?

When you connect a standalone battery to a voltmeter the voltmeter reads 5 V. (a) Assuming the voltmeter has a very high resistance, what is the approximate elec- tromotive force in the battery? (b) When you hook the same battery up to a circuit with a 15 Ohm resistor, you hook up the voltmeter to read the terminal voltage across the battery and it now reads 4.688 V instead of 5 V. What is the internal resistance of the battery?

A light bulb and a resistor are connected in series to a variable power supply. A student first connects a voltmeter and an ammeter to measure the current through and the voltage across the bulb, as shown in the left circuit below. The student varies the power supply voltage and records the readings on the meters. Power Supply Power Supply The student then places the voltmeter across the resistor as shown in the right circuit above, and repeats the experiment....
