Table 1

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

  1. What is the value of the resistance, with error limits?

  2. If three similar resistors are used in the circuit shown in Figure 1, what is the voltage across R3?

Figure 1   A voltage divider circuit is shown.
