The potential difference across the filament of a light-bulb is maintained at a constant value while equilibrium temperature is being reached. The steady-state current in the bulb is only one-tenth of the current drawn by the bulb when it is first turned on. If the temperature coefficient of resistivity for the bulb at 20.0C is 0.004 50 (C)-1 and the resistance increases linearly with increasing temperature, what is the final operating temperature of the filament?
when a potential difference of 10.0V is placed across a certain soild cylindrical resistor, the current through it is 2.0A. If the diameter of this resistor is now doubled, the current will be?2.0A18.0A8.0A3.0A
as part of a lecture demonstration, a physics professor plans to hold an ununsulated current carrying wire in her hands. For safety sake, the potential differnece between her hands is to be no more that 1.50v. She holds her hands 1.20m apart, with the wire stretched tightly between them. The wire is to carry 6.00 A of current and is to be made of aluminum. What is the minimum wire radius that is consistent with safety? p for aluminimum = 2.75 x 10 -8 omega-m
The resistance of the body varies from approximately 500 kΩkΩ (when it is very dry) to about 1.0 kΩkΩ (when it is wet). The maximum safe current is about 5.3 mAmA. At 10 mAmA or above, muscle contractions can occur that may be fatal. What is the largest potential difference that a person can safely touch if his body is wet?

While taking photographs in Death Valley on a day when the temperature is 58.0C, Bill Hiker finds that a certain voltage applied to a copper wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is 88.0C? Assume that no change occurs in the wires shape and size.
