Chapter 18 Lab Report
The purpose of this lab report is to show how ohms law applies to voltage
and resistance. It also, shows the effect of wire length on the amount of voltage
delivered. The importance of this experiment is to predict how

1. A certain laboratory experiment requires an aluminum wire of length of 37.0 m and
a resistance of 3.50 at 20.0C. What diameter wire must be used? (The resistivity
of aluminum at 20.0C is 2.82 10-8 m.)
R/P = L/A
Chapter 16: Electric Energy and Capacitance
The purpose of the experiment is to show the relationship between electric energy
and distance. The first section shows the definition of an equipotential line in order
to understand how electric f
Chapter 19 Lab Activity Part 1
The purpose of this experiment is to understand how magnetic fields work.
They are explained as opposites attract and likes repel. This is explained through the
direction the compass points when it is placed at
Batteries, Resistance and Current
Electric current is the rate at which the charge flows through a surface; it is
measured in Ampere (A), which is Coulombs/Seconds. The direction of the current
is the direction to where the positive charge w

1. The two charges in the figure below are separated by d = 4.00 cm.
(Let q1 = 15.5 nC and q2 = 29.5 nC.)
(a) Find the electric potential at point A.
Since Voltage is scalar then V1+V2 = V
V1 = K (q1/r) = (8.99*10^9)(-15.5*10^-9)/(4*1
Chapter 19 Lab Activity Part 2
Answer the following questions:
1. A wire is formed into a circle having a diameter of 10.7 cm and is placed in a
uniform magnetic field of 3.22 mT. The wire carries a current of 5.00 A. Find the
maximum torque on the wire.

1. Gold is the most ductile of all metals. For example, one gram of gold can be
drawn into a wire 2.35 km long. What is the resistance of such a wire at 20C?
(The density of gold at 20C is 1.93 104 kg/m3.)
