Chapter 11
When power supplies are connected in parallel, the voltage remains the same, but the current or amp-hour capacity will be increased.
True
The product-over-sum method is used to calculate the resistance of _____ resistance(s) at a time.
Two
The total resistance of a parallel circuit can be calculated by the _____ method.
Equal resistance Product-over-sum Reciprocal
According to the equal resistance method, when all the resistances of the parallel circuit have the same resistance, divide the resistance of one element by the largest resistor in parallel.
False
In a parallel circuit, the total circuit resistance is always greater than the smallest resistance.
False
In a parallel circuit, the voltage drop across each resistance is equal to the sum of the voltage drops of each of the resistors in parallel.
False
A parallel circuit has two or more paths in which current may flow.
True
According to Kirchoff's Current Law, the total current provided by the source to a parallel circuit equals the sum of the currents of all of the branches.
True
The advantage of the reciprocal method is that the formula can be used for as many resistances as the parallel circuit contains.
True
The total power consumed in a parallel circuit equals the sum of the power of all branchs.
True
