One Ampere is one Coulomb of charge flowing through a circuit in how many seconds?
4.
Oerstead used the current flowing in a wire due to a voltaic pile to show the link
between electricity and magnetism, today simply known as _________________________.
5.
Wheatstone and Ohm showed that the telegraph signal could be sent over large
distances if the ____________ was increased in proportion to _______________.
6.
State Ohm’s Law in equation form and describe what it means in words.
7.
Analogous to water pipes, the resistance of a resistor is…..
R  ________ ;
R  ____________ ; and
R  constant/__________
8.
If conductors are connected to a battery, an electric field is created inside a conductor,
hence the valence electrons flow. What creates the “resistance”?
9.
Applying the concept of conservation of charge, Kirchhoff developed the “junction rule”.
It says “the current flowing into a junction __________ the current flowing _______ of the
junction.

Kirchhoff other law states that as a charge flows around a complete circuit, it neither
_________ or __________ energy.
