A resistor with an unknown value (R) has 9V applied to it from a battery. The resistor wastes 1.34 W of power as heat. a. What is the current flowing through the resistor? b. What is the resistance of R? c. If R was powered by a 12V battery, how much power will be dissipated as heat? d. Can you think of an example were we use resistive elements for heating?
