Given the circuit in Fig. P2.46.

(a) find the required value of R.
(b) use Table 2.1 to select a standard 10% tolerance resistor for R.
(c) calculate the actual value of I.
(d) determine the percent error between the actual value of I and that shown in the circuit.
(e) determine the power rating for the resistor R.
