A long copper wire has a resistance of 33 Ohms. A second copper wire is a factor of 5 times shorter than the first wire. (It is the same area, however.) If the second wire is connected to a 24 volt battery, what is the current in the wire in amps?
Homework Answers
A long copper wire has a resistance of 33 Ohms
R1=33 ohm
5 times so
R2=33/5
I2=V/R2

A wire which is 6 km long made of copper is connected to a battery. Because it is very long, its resistance is not neglected and the power dissipated by the wire alone is 12 watts. The same wire is melted down and shaped into another wire. When this wire is connected to the same battery, it dissipates 74 watts. What is the length of the second wire in km? please show your work

A thick copper wire 2.3 m long is connected in series to a thin high-resistance Nichrome wire. In the steady state, the conventional current in the thick copper wire is 4 amperes. In this copper wire there are 8 � 1028 mobile electrons per cubic meter and the electron mobility is 4.5 � 10?3 (m/s)/(V/m). The cross-sectional area of the copper wire is 6 � 10?7 m2. The thin high-resistance Nichrome wire (which is connected in series to the thick...

a piece of copper wire of resistance R is cut into 10 equal lengths. These parts are connected in parallel. How does the joint resistance of the parallel combination compare with the original resistance of the single wire? The circuits, P and Q, show two different ammeter-voltmeter methods of measuring resistance. Suppose the ammeter has a resistance of 0.10 ohms and the voltmeter of 3.0 ohms; the ammeter reads 2.5 amps and the voltmeter reads 6.0 volts. What is the...

A long copper wire is used to transmit a current from one side of the campus to another as part of a scientific experiment to measure the speed of sound. The wire has a cross sectional area of 2.5*10^-6 m^2 and a total resistance of 7.2 ohms. A voltage of 25 V is applied across the length of the wire. The resistivity of copper is 1.68*10^-8 ohms m. How long is the wire? What is the current flowing through the...
