Deck 4: Parallel Circuits

Question 1

In a parallel circuit, each resistor operates at the same voltage as the ____________________.

Answer 1

source

Question 2

Why shouldn't an electrical component ever be placed in a parallel circuit if it has a voltage rating less than the source voltage?

Answer 2

In a parallel circuit, each resistor is placed directly across the main source of voltage. This causes each resistor to operate at the same voltage as the source. Therefore, each electrical component in a parallel circuit must have a voltage rating greater than the voltage source.

Question 3

In a parallel circuit, the total resistance will always be less than the smallest R in the circuit when two or more resistors are present.

Answer 3

True

Question 4

The components in a parallel circuit operate independently of one another.

Question 5

Adding parallel branches to a circuit increases the total resistance.

Question 6

A(n) ____________________ circuit has more than one path for current.

Question 7

It is acceptable to place an electrical component in a parallel circuit if it has a voltage rating less than the source voltage.

Question 8

If you can apply a known source voltage, but you do not know the resistance of the individual resistors in a parallel circuit, how can you determine the total resistance in the circuit?

Question 9

The total current in a parallel circuit is equal to the ____________________ of the currents in the separate components.

Question 10

A simple method of solving circuits consisting of only two resistors in parallel (with either equal or unequal values) is called the "____________________ over the sum" method.
