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 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...
