Solution to Frame 118

The relationships among current, voltage and

a. increases

resistance were first expressed by George Ohm.

"Ohm's Law" states that the current is directly

b. decreases

proportional to applied voltage and inversely

proportional to resistance. Since this relationship

c. decreases

was first recognized by Ohm, this principle is named

after him. We call it ____________ law.

d. increases

Solution to Frame 119

Ohm's Law states that:

Ohm's

a. If voltage is increased, the current

_________________________________ .

b. If voltage is decreased, the current

_________________________________ .

c. If resistance is increased, the current

_________________________________ .

d. If resistance is decreased, the current

_________________________________ .

Solution to Frame 120

Ohm's law can be expressed as a formula. The

a. increases

basic formula is I = E/R (current = voltage divided

by resistance). There are other ways of writing

b. decreases

Ohm's law, but the basic way is I = _______.

c. decreases

d. increases
