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...

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?

PROCEDURE: 1. Resistors in series: Connect the circuit shown in Fig. 1. Using circuit theory (Ohms Law in conjunction with the predicted procedure for combining resistors in series), calculate the expected current in or through the three resistors in series and the expected voltage across each of the three resistors.

With the given information, what are the following
values?
Also, sorry for the picture quality. it was the best I could
do.
The voltage is 0.528 V(in volts) and the current is in
amperes. However, I think it needs to be converting to mA. So, I
believe the current is 0.1483 mA, 0.0925 mA, 0.00498 mA.

Part C: Post Lab Questions for Lab 9 Complete the Lab before you work on these four questions (1) Ohm's Law is v= 1 R, the Voltage [Volts] = Current [Amp] x Resistance [Ohms]. The current that flows through the battery depends on the total resistance in the circuit and the voltage of the battery. In the following circuit, a 10 Volt battery is connected in series with three resistors: Ri-1000 Ohms, R-500 Ohms, and R1-1500 Ohms a. What is...
