Unit 3 flashcard 1

Front

What do AC generators convert to electrical energy?

Back

Mechanical energy

Front

In what form does a capacitor store electrical charge between its plates?

Back

Electrostatic Field

Front

What is the formula for calculating total capacitive reactance in a parallel circuit?

Back

Total capacitive reactance (Xc) = 1 / (1/Xc1 + 1/Xc2 + ... + 1/Xcn) where Xc is the capacitive reactance of each capacitor.

Front

How do you calculate the inductive reactance of a circuit?

Back

Inductive reactance (Xl) = 2πfL, where f is the frequency in Hz and L is the inductance in Henries.

Front

What is the relationship between frequency and period in an AC sine wave?

Back

Frequency (f) = 1 / Period (T), where T is the period in seconds.

Front

What is the unit of measurement for capacitive reactance?

Back

Ohms (Ω)

Front

What is the unit of measurement for inductive reactance?

Back

Ohms (Ω)

Front

How do you convert frequency from Hz to GHz?

Back

To convert from Hz to GHz, divide the frequency in Hz by 1,000,000,000.

Front

What is the formula for calculating the total capacitance of capacitors in parallel?

Back

Total capacitance (C_total) = C1 + C2 + ... + Cn, where C is the capacitance of each capacitor.

Front

What is the significance of the electrostatic field in capacitors?

Back

The electrostatic field is the region around a charged capacitor where electric forces can be felt, and it is responsible for storing energy.
