PLEASE answer question 5 and 6

PmW IMA . . V (sold Fig. 4.4 If you double the applied voltage from 4 V to 8 V, does the power increase by the same factor as it did from 3 V to 6V? 5. If you triple the applied voltage, how many times does the power increase? 6. What relationship is there between the power and the current flowing? 7. Plot Fig. 4.5 for power against R, by using data from Table 4.2. Power (W Fig. 4.5 Lood resistance 8. What is the power dissipated in Rat R-470 ? CONCLUSION
