Resistance

a material's opposition to the flow of electric current; measured in ohms;

The electrical resistance of an electrical conductor is a measure of thedifficulty to pass an electric current through that conductor.unit of resistance is ohm

electric resistance、 electrical resistance、 impedance、 resistivity、 ohmic resistance

阻力；电阻；抵抗；反抗；抵抗力

a resistor

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. 

电阻器

load

The load is what the circuit powers and every circuit has at least one.

负载

resistive,

exhibiting or relating to electrical resistance

电阻的

capacitive

of or relating to capacitance

电容性的

inductive

arising from inductance

感应的；归纳法；电感的；诱导的

open circuit

an incomplete electrical circuit in which no current flows

[电] 开路

closed circuit

the circuit is connected - current flows in the circuit

Kirchhoff's Laws

An important important of electrical circuits

基尔霍夫定律

Kirchhoff’s Current Law

The net current entering a node is zero.We abbreviate Kirchhoff’s current Law as KCL.

基尔霍夫电压定律

Kirchhoff’s Voltage Law

The algebraic sum of the voltages equals zero for any closed path (loop) in an electrical circuit.We abbreviate Kirchhoff’s Voltage Law as KVL.

基尔霍夫电流定律

blows

a resistor, fuse, diode, etc. break the circuit - go open circuit

断开

limit

the value that a function or sequence "approaches" as the input or index approaches some value

LED

Light emitting diode
