4. Ohm’s Law: relates voltage, amperage, and
resistance
• Ohm’s law states that voltage is the product of
resistance times current.
• It is written as V = I x R.
• In simplest terms, it goes like this:
It takes 1 volt to push 1 amp through a resis-
tance of 1 ohm (1 = 1 x 1).
• This equation can be rearranged using algebra
to solve for any one variable.
• Those who were traumatized by algebra can
represent Ohm’s law as a triangle. When using
the triangle, cover the value to be found, and the
two values left exposed signify how to obtain that
value. See Figure 7.25.
• As an example if the “R” is covered, the “V” is
over the “I” which means “V” divided by ”I” will
solve for the covered letter “R” (V/I = R). If the
“V” is covered, “I” and “R” are exposed on the
same line, meaning that the product of “I” times
“R” will solve for the unknown “V” (I x R = V).
5. Kirchhoff’s current law:
• Kirchhoff’s current law deals with nodes. Nodes
are the junction of two or more wires or the junc-
tion of a wire to a component.
• Kirchhoff’s current law states that what ever cur-
rent goes into a node must come out.
• As an example: Three wires are connected with
a wire nut. One wire has 5 amps going into the
connection.
• The sum of the currents coming out of the other
two wires must equal 5 amps. That could be 3
amps in one wire and 2 amps in the other or it
could be 2.5 amps in each wire, but the total
coming out must be the same as the current
going in. See Figure 7.26.
