So far you have learned that in a series circuit:
8 amp
It = Et = 80v_ = 8 amp
a. There is/are (only one/more than one) path for the current
Rt 10Ω
to flow.
b. I (current) has (the same/a different) value(s) everywhere
in the circuit
c. To get Rt, you (sum/subtract) the individual voltage
d. To get Et, you (sum/subtract) the individual voltage drops.
e. Et and Ea (are/are not) the same.
f. To find I, you (must/must not) use Rt.
g. To find I, you (must/must not) use either Et or Ea.
Solution to Frame 44
FRAME 45
The statement "The greater the resistance, the greater the
a. only one
voltage drop" does not tell you how to calculate the exact
b. the same
voltage drop. However, Ohm's law does allow you to
c. sum

d. sum
e. are
f. must
