Ohm’s legislation states that the present flowing by way of a sequence circuit is instantly 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 way of 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 results of resistance on present move, you possibly can predict the habits of the circuit and calculate the values of present, voltage, and resistance.
7. Purposes
Sequence circuits are utilized in all kinds {of electrical} and digital purposes, corresponding to voltage dividers, present limiters, and timing circuits.
