Circuit Elements Flashcards
What is Ohm’s Law?
V=iR
What is the iV equation for a resistor?
V=iR
What is the iV equation for a capacitor?
i=C(dV/dt)
What is the iV equation for an inductor?
V=L(di/dt)
What is the symbol used for inductance?
L
What does an iV equation do?
Tells us what relates current to voltage
What does it mean when something is ‘ideal’?
It is mathematically perfect
What are three types of ideal sources?
Constant voltage, battery, and constant current
What do you call the parts of a circuit?
Components or elements/branches
What is a mesh?
“Gaps” in circuits
What is a loop?
A closed path going through circuit elements
Which terminals does current go into and out of?
Current goes in the + terminal and out of the - terminal
How does one draw a resistor?
Rectangle with two lines coming out
How does one draw a capacitor?
Two lines with two lines coming out
How does one draw an inductor?
Loop-de-loop
What is the evil way to draw a resistor?
Zig-zag
How does one draw a battery?
Two long lines, two short lines
On a drawing of a battery, which is the + and which is the - terminal?
The long line is + and the short line is -
How does one draw constant voltage?
Circle with + and - inside
How does one draw constant current?
Circle with an arrow inside
What does a resistor do?
Limits or regulates flow of electrical current
What does a capacitor do?
Stores and releases electricity in a circuit (static?)
What does an inductor do?
Stores energy in the form of magnetic energy
