You have a simple circuit consisting of a battery and a lightbulb (you can imagine that this circuit is contained within a flashlight).  If the total potential difference provided by the batteries in this circuit is 6V, and if you measure the current to be 17.08mA, what is the resistance of the light bulb (created by the thin wire which composes the filament) in units of Ohms?

You have a simple circuit consisting of a battery and a lightbulb (you can imagine that this circuit is contained within a flashlight).  If the total potential difference provided by the batteries in this circuit is 6V, and if you measure the current to be 23.04mA, what is the resistance of the light bulb (created by the thin wire which composes the filament) in units of Ohms?

A resistor is dissipating 119milliwatts​ [mW] of power. The voltage across the resistor is 26 volts​ [V]. ​(a) What is the value of the​ resistance? Express your answer in units of ohms​[Ω​]using an appropriate SI prefix such that there are only​ one, two, or three digits shown to the left of the decimal. ​(b) What is the current through the​ resistor? Express your answer in units of amperes​ [A] using an appropriate SI prefix such that there are only​ one, two, or three digits shown to the left of the decimal.

Someone has given you a light bulb and asked you to figure it out the materials of the filament of a light bulb made from. You placed the light bulb in the bulb holder and with the help of multimeter, you measured a current of 0.830 A passing through the bulb and voltage of 1.20 x 102 V across the bulb. When you solve the problem, please use the length of the filament as 6.00 x 10¹ cm and diameter of the wire as 9.50 x 10-3 mm. Hint: You simply find the resistivity of the material and then compare your value from the table provided here. After that tell me the name of the material of the filament. Is it tungsten or something else? Material Copper Aluminum Tungsten (20°C) Tungsten (1500°C) Iron Nichrome Search Resistivity (2.m) 1.7x10-8 2.7x10- 5.6x10-8 5.0×10-7 9.7x10-8 1.5×10- H

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?
