Ohm’s legislation states that the present flowing by a sequence circuit is immediately proportional to the voltage utilized to the circuit and inversely proportional to the resistance of the circuit.
5. Equal Resistance
The equal resistance of a sequence circuit is the sum of the resistances of all of the resistors within the circuit. The equal resistance determines the general present that flows by the circuit.
6. Circuit Evaluation
To investigate a sequence circuit, you should utilize Ohm’s legislation and the idea of equal resistance. By understanding the consequences of resistance on present circulation, you may predict the habits of the circuit and calculate the values of present, voltage, and resistance.
7. Functions
Sequence circuits are utilized in all kinds {of electrical} and digital purposes, comparable to voltage dividers, present limiters, and timing circuits. By manipulating the resistance values, you may management the quantity of present flowing by the circuit and obtain desired circuit traits.
