Ash is working in the lab, and comes across a box of unlabeled resistors (thanks to his messy coworker who never puts them back properly). He remembers that he can find out the resistance using an ammeter to measure current, and a battery with a known voltage. Ash picks a resistor of unknown resistance (in №), connects it to some wires, and then plugs in a battery with a voltage of 12.1 V. This creates a circuit. Using the ammeter, he finds that the current in the circuit is 5.2 A. In ohms, what is the resistance of the unknown resistor? Answer: Ω.

Lightbulb A is marked 25.0 W 120. V, and lightbulb B is marked 100. W 120. V.

Review. When a straight wire is warmed, its resistance is given by R = R0,[1 + a(T T0)] according to Equation 27.20, where a is the temperature coefficient of resistivity. This expression needs to be modified if we include the change in dimensions of the wire due to thermal expansion. For a copper wire of radius 0.100 0 mm and length 2.000 m, find its resistance at 100.0C, including the effects of both thermal expansion and temperature variation of resistivity. Assume the coefficients are known to four significant figures.
Resistors are commonly rated at 18W,14W,12W ,1 W and 2 W for use in electrical circuits. If a current of1 = 2.00 A is accidentally passed through a R=1.00 resistor rated at 1 W, what would be the most probable outcome? Is there anything that can be done to prevent such an accident?
