Parallel connection of resistors
To determine the total equivalent resistance, you can use an accurate and convenient calculator. Where, by entering data on the number of resistors, the calculator will perform the calculation automatically.
This connection is one of the 2 types, in this case, both terminals of one resistor are connected to the terminals of the second resistor. In other cases, they are connected in parallel or series to create complex circuit schemes.
To find the current flowing through a specific resistor, you should use the formula:
Let's perform calculations according to the example
A device is being developed that requires the use of a resistor with a resistance of 8 Ohms. Since the nominal series according to the standard values of such resistors does not exist, the solution will be to use 2 resistors connected in parallel.
For such a method, the following calculations are made:
This formula shows that if R1 = R2, R will be exactly half of the resistance of one of the two resistors.
And if R=8 Ohms, then accordingly R1 and R2 = 2*8=16 Ohms.
