Deck 10: Summary Review of

Question 1

In a series circuit, the voltage is the same through each device.

Answer 1

False

Question 2

A 5-ohm, an 10-ohm, and a 15-ohm resistor are connected in series. The voltage across the 10-ohm resistor is 50 volts. Determine the supply voltage. (Assume conductor resistance is negligible.)

Answer 2

Since the resistors are connected in series, the current traveling through each resistor is exactly the same.
E = IR
I = E/R = 50 volts/10 ohms = 5 amperes
ET = IRT
ET = (5 amperes)*(5 ohms + 10 ohms + 15 ohms) = 150 volts

Question 3

In the accompanying figure, the two resistors in the circuit are connected in ____________________ with one another.

Answer 3

parallel

Question 4

Ohm's law states I=R/E.

Question 5

____________________ defines the basic electrical relationships of current, voltage, and resistance.

Question 6

In a parallel circuit, the current is the same across each branch.

Question 7

The condition of a lead-acid battery can only be determined by checking the specific gravity of the ____________________.

Question 8

Electrons move through wires to create ____________________.

Question 9

If voltage remains constant and resistance increases, current will decrease.

Question 10

A 5-ohm, an 10-ohm, and a 15-ohm resistor are connected in parallel. The current through the 10-ohm resistor is 5 amperes. Determine the supply voltage. (Assume conductor resistance is negligible.)
