Example
2.2.4 Resistor
Resistor is an electronic element that can limit the branch current. A fixed resistor is a kind of resistor whose resistance
cannot be changed, while that of a potentiometer or a variable resistor can be adjusted.
Two generally used circuit symbols for resistor. Normally, the resistance is marked on it. So if you see these symbols
in a circuit, it stands for a resistor.
is the unit of resistance and the larger units include K, M, etc. Their relationship can be shown as follows: 1 M=1000
K, 1 K = 1000 . Normally, the value of resistance is marked on it.
When using a resistor, we need to know its resistance first. Here are two methods: you can observe the bands on the
resistor, or use a multimeter to measure the resistance. You are recommended to use the first method as it is more
convenient and faster.
