Mathematics and Electrical Concepts Quiz

Radian and Degree Conversion

• 1 radian is equal to 57.3 degrees.
• 4800 mils are equal to 270 degrees.

Algebraic Equation for a Straight Line

• The equation "y = a₁ + a₂x" represents a straight line.

Acid Test Ratio

• The acid test ratio is calculated by dividing current assets (excluding inventory) by total current liabilities.

Electrical Concepts

• Voltage, also known as potential difference, is the energy required to move 1 Coulomb of charge.
• Current is the rate of charge flow.
• Power is the rate at which energy is transferred.

Number Sequences

• The Fibonacci sequence is a number sequence where each succeeding term is obtained by adding the last two preceding terms.

Solutions to Equations

• Trivial solutions are solutions to an equation where the roots are zero.

Electrical Laws and Units

• Kirchhoff's current law states that the algebraic sum of currents entering a node is zero.
• Kirchhoff's voltage law states that the algebraic sum of all voltages around a closed path is zero.
• The SI unit of conductance is Siemens.
• 1 Ampere is equivalent to 1 Coulomb per second.

Mathematical Concepts

• Factoring is the process of expressing a polynomial as the product of another polynomial or monomial of lower degree.
• A point of inflection is where the concavity of a curve changes, or where the slope of the curve is neither increasing nor decreasing.
• The transverse axis of a hyperbola passes through the center, foci, and vertices.

Irrational Numbers

• An irrational number cannot be expressed as a quotient of two integers.

Electrical Energy & Charge

• The energy required to move 1 Coulomb of charge through an element is called voltage.

Fibonacci Sequence

• The Fibonacci sequence is a number sequence where each term is the sum of the two preceding terms (e.g., 1, 1, 2, 3, 5, 8...).

Types of Solutions in Equations

• If the roots of an equation are zero, the solutions are classified as trivial solutions.

Electrical Current

Polynomial Factoring

• Factoring is the process of expressing a polynomial as the product of other polynomials or monomials with lower degrees.

Point of Inflection

• A point of inflection is where the concavity of a curve changes, and the slope of the curve is neither increasing nor decreasing.

Hyperbola Axis

• The transverse axis of a hyperbola passes through the center, foci, and vertices.
