b
According to Ohm's Law, an electrical circuit with a driving voltage of 12 Volts
and a resistance of 10 Ohms produces a current of...(Amps)
1.2 A
Kirchoff's Current Law
the total current entering a circuit branch must equal the current leaving the branch

the sum of the voltage drops in a series circuit must equal the circuit's total voltage
In a series electrical circuit
a) current is different across each resistor
b) Kirchoff's Voltage Law is obeyed
c) voltage is the same across each resistor
d) total resistance is the sum of the reciprocal of each resistance
b
In a parallel electrical circuit
a) total resistance is the sum of all of the resistors
b) current is the same through each resistor
c) voltage is different across each resistor
d) voltage is the same across each resistor
d
The driving voltage of an electrical circuit with a resistance of 1 Ohm and 100 mA
is...(Volts)
0.1 V
What is the total resistance in a series circuit consisting of three resistances: 1
Ohm, 2 Ohms, and 10 Ohms?
, 13 Ohms
If a resistance of 0.17 Ohms was measured across a conductive material L = 1 m,
D = 10 cm, what is its resistivity?
0.13 Ohm-cm
Cations are _____ charged ions
positively
Anions are ______ charged ions
negatively
Which of the follow is true about an electrochemical cell?
a) as polarization decreases, current will decrease
b) as polarization increases, current will decrease
c) as polarization increases, there is no change in current
d) as polarization decreases, there is a decrease in driving voltage
b
Why does corrosion rate decrease as polarization increases?
polarization lowers potential difference between anode and cathode, causing a
reduction in corrosion current and corrosion rate
The weight of any material deposited on the cathode or released from the anode
is
a) directly proportional to the current
b) directly proportional to the total resistance
c) inversely proportional to the current
d) inversely proportional to the resistance
a
Oxidation
a) increases the negative charge of an atom or compound
b) decreases the positive charge of an atom or compound
c) is independent of reduction
d) occurs when the electrons are lost from an atom or compound
d
Electrochemical corrosion requires
a) an anode and electronic path
b) a cathode and electrolyte
c) an anode, a cathode, and an electronic path
d) an anode, a cathode, an electrolyte, and an electronic path
d
In an anodic process
a) positively charged ions leave the anode and enter the electrolyte
b) electrons flow through the electronic path from cathode to anode
c) negatively charged ions leave the anode and enter the electrolyte
d) positively charged ions leave the cathode and enter the electrolyte
