Houston spring final exam
Part 1: Fundamentals, KCL, KVL, and Series/Parallel (Q1 - Q30)
Q1. According to Ohm's Law, if the voltage across a resistor is 12 V and the
current through it is 3 A, the resistance is:
A)
36
Ω
36Ω
B)
4
Ω
,4Ω
C)
15
Ω
15Ω
D)
0.25
Ω
0.25Ω
Answer: B)
4
Ω
4Ω
Rationale: Ohm's Law states

=
I
R
V=IR. Solving for
R

R=V/I=12V/3A=4Ω.
Q2. A current of 2 mA flows through a 5 kΩ resistor. The voltage drop across the
resistor is:
A) 10 V
B) 2.5 V
C) 0.4 V
D) 10,000 V
Answer: A) 10 V
Rationale: Using
V
