In controlling a voltage or current, resistors always follow Ohm’s Law. This means that the current and voltage ‘drop’ are interdependent; if a precise reference voltage is required, then the current must also be controlled precisely.

How do resistors affect capacitors? Resistors are often used in combination with capacitors in order to control the charge and discharge time necessary for the intended

AI Customer ServiceA capacitor can be charged or discharged gradually by connecting it in series with a resistor (and if charging, a voltage source). The voltages and currents in the circuit are decaying exponential functions of time.
AI Customer ServiceResistors, capacitors, and inductors are not only classic building blocks of circuits. They inform us about the nature of the properties of resistance, capacitance, and inductance. Even a bare wire has some resistance, some capacitance, and some inductance.
Resistors are used in virtually every circuit. A few examples are voltage dividers, filters, and biased active circuits. Capacitors store and release electric charge (kind of like a battery). Their properties are different in DC vs. AC circuits but can be useful in both.
The study of resistors, capacitors and inductors allows us to gain a deeper intuition of some of the most important principles that affect the design and operation every circuit. This is because every circuit has resistance, capacitance, and inductance even if they don’t contain resistors, capacitors, or inductors.
A resistor is just an imperfect conductor, and you can make a resistor just by using a really long wire (as wires themselves have some resistance). Resistors are used in virtually every circuit. A few examples are voltage dividers, filters, and biased active circuits. Capacitors store and release electric charge (kind of like a battery).
Another technique to form capacitors, is to use the depletion region, which is formed between p n junction. The junction capacitance value is important for circuit design since it a ects the speed of the circuit. The natural junction capacitance has the e ect of slowing down the circuit.
