In a series circuit
a) voltage drops are always equal
b) total resistance equals the sum of individual resistances
c) current varies through resistors
d) total current is equal to the sum of the current through each resistor - ANSWER-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) - ANSWER-1.2 A
Kirchoff's Current Law - ANSWER-the total current entering a circuit branch must equal the current leaving the branch
Kirchoff's Voltage Law - ANSWER-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 - ANSWER-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 - ANSWER-d The driving voltage of an electrical circuit with a resistance of 1 Ohm and 100 mA is...
(Volts) - ANSWER-0.1 V
What is the total resistance in a series circuit consisting of three resistances: 1 Ohm, 2 Ohms, and 10 Ohms? - ANSWER-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? - ANSWER-0.13 Ohm-cm
Cations are _____ charged ions - ANSWER-positively
Anions are ______ charged ions - ANSWER-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 - ANSWER-b
Why does corrosion rate decrease as polarization increases? - ANSWER-polarization lowers potential difference between anode and cathode, causing a reduction in corrosion current and corrosion rate
