Question 1

Write the formula for the reciprocal method of calculating total resistance for any number of resistors in parallel.

Accepted Answer

RT = 1/(1/R1 + 1/R2 + 1/R3 + 1/R4)

Question 2

Series-parallel circuits are calculated with parallel rules only.

Accepted Answer

Series-parallel circuits are calculated using both series and parallel rules, depending on the configuration of components within the circuit.

Question 3

In a parallel circuit, branches that are in parallel have different voltage drops across them.

Accepted Answer

In a parallel circuit, all components or branches that are in parallel have the same voltage across them.

Question 4

The first step in evaluating a(n) _______________ circuit is to determine the series parts and parallel parts.

Accepted Answer

The answer of The first step in evaluating a(n) _______________...

Question 5

Explain the difference between constant current and constant voltage.

Accepted Answer

The answer of Explain the difference between constant current and...

Question 6

In a parallel circuit, as branches are added, total current increases.

Accepted Answer

In a parallel circuit, adding more branches creates additional paths for the current to flow, which reduces the overall resistance of the circuit and increases the total current.

Question 7

Explain Kirchhoff's Current Law.

Accepted Answer

The answer of Explain Kirchhoff's Current Law....

Question 8

Constant current sources supply constant current to a load rather than constant ____________.

Accepted Answer

The answer of Constant current sources supply constant current to...

Question 9

A parallel circuit is a current multiplier because current accumulates at each branch.

Accepted Answer

In a parallel circuit, the voltage across each branch is the same, but the current is divided among the branches, not multiplied.

Question 10

In a parallel circuit, the voltage drop across a branch is equal to the __________ voltage of that branch.

Accepted Answer

The answer of In a parallel circuit, the voltage drop...

Question 11

What happens to the current when resistance is added to a parallel circuit?

Accepted Answer

The answer of What happens to the current when resistance...

Question 12

Ohm's Law states that when voltage is held constant and __________ increases, then current decreases.

Accepted Answer

The answer of Ohm's Law states that when voltage is...

Question 13

In a parallel circuit, the total current is the sum of the branch currents.

Accepted Answer

In a parallel circuit, the total current flowing from the power source is divided among the parallel branches, and the sum of the currents in each branch equals the total current flowing in the circuit.

Question 14

In a parallel circuit, the loads and resistors are connected in a manner such that there is more than one ______________ for current flow.

Accepted Answer

The answer of In a parallel circuit, the loads and...
