Fourth Period Math Applications

Question 2

Describe Kirchoffs Voltage Law:

Answer 2

The total voltage rise or applied voltage equals the total voltage drops in a circuit.

Question 3

What value is equal in each branch of a Parallel circuit?

Answer 3

Voltage

Question 4

Describe Ohm’s Law:

Answer 4

Voltage is directly proportional to Current and inversely proportional to Resistance

Question 5

What is the formula for solving total resistance in a Parallel circuit?

Answer 5

Rt = (R1^-1 + R2^-1 + R3^-1) -1

Question 6

A series-parallel circuit has one path for current to flow. T or F?

Answer 6

False.

Question 7

Name the sides of a right angle triangle:

Answer 7

Hypotenuse, the adjacent side and the opposite side

Question 8

The combined effect of resistance, inductive reactance and capacitive reactance in a circuit is called?

Answer 8

Impedance - A.C circuit

Question 9

Inductive reactance causes current to ______ voltage

Answer 9

Lag , E.L.I

Question 10

Describe Capacitance:

Answer 10

The property of a circuit that allows it to store energy in the electrostatic field and release it back to the circuit. Because a capacitor is a DEVICE that stores and releases energy, it has a tendency to oppose any change in VOLTAGE.

Question 11

Describe the phase angle:

Answer 11

The number of degrees by which the current through a component leads or lags the voltage across the component.

Question 12

State another name for True Power or Power (P) in a circuit:

Answer 12

Real or active power.

Question 13

State a formula for the power factor other than
P/S:

Answer 13

R/Z or W/VA
