9. List 4 ways to increase the resistance of a circuit: 10. What are four ways you can increase the resistance of a wire? 11. If IC flows through a wire in 5sec, what is the current? (I=0.ZA) 12. If the current is 0.1 A and a bulb has 100-ohms of resistance, (V=(Ov) how much voltage is established in the circuit? 13. A 12v battery is connected to a bulb. If 3A flows, what is the resistance? ( R = 4 ) 13. A resistor of 18-ohms is connected to a 12v battery. What is the current? (I=Odd7A) 14. If an appliance plugged into a socket (120v) draws 5A, how much power does it use? (?=(cow) 15. A light bulb on for 10s uses 600J of energy. How much power did it put out? (P=GOw) 16. If you leave a 100W bulb on for 1 hr, how much energy do you use? (He =100 Whr, f*) (If it costs $0.40/kw*hr, how much does it cost?)
