Lab 2 Circuits

Table 1
R = 2.09K ± 80 Ohms
The current flowing in Figure 1 is 9V/3R.
The Voltage across R V = R*I = R*9/3R = 3V |

**Lab 2 Exercise**

Table 1 contains measured values of the current through a resistor as a function of the voltage across the resistor.

- What is the value of the resistance, with error limits?
- If three similar resistors are used in the circuit shown in Figure 1,
what is the voltage across R
_{3}?

Figure 1 A voltage divider circuit is shown.
