- A common flashlight bulb is rated at 0.34 A and 2.3 V (the values of the current and voltage under operating conditions). If the resistance of the bulb filament at room temperature (20°C) is 1.0 2, what is the temperature of the filament when the bulb is on? The temperature coefficient of resistivity is 3.7 x 10-3 K-1 for the filament material.Consider the following circuit diagram. The potential difference across the battery is 40.0 volts, and it supplies a current of 5.00 amperes to the circuit. There is a current of of 2.70 amperes flowing through R1. Resistor R2 has a resistance of 5.50 ohms. What is the resistance of R3? Answer in ohms to two decimal places, but do not include units in your answer.What is the resistance (in Ohms) of a wire made of a material with a resistivity of 3.3x 10-82. m if its length is 4 m and its diameter is 0.64 mm?
- Resistance, R, is defined using R = V/I where V is the potential across a resistor, and I is thecurrent. R is measured in ohms (Ω), where 1 Ω = 1 V/A. The constant you determined in eachequation should be similar to the resistance of each resistor. However, resistors aremanufactured such that their actual value is within a tolerance. For many common resistors, thetolerance is 5% or 10%. Calculate the range of possible values for each resistor. Does the constant in each equation fit within the appropriate range of values for each resistor? Do the resistors follow Ohm’s law? Base your answer on your experimental data.
