. Series Connection:
a. Calculate the total resistance of a series circuit with three resistors of 10Ω, 15Ω, and 20Ω connected in series.
The total resistance of a series circuit is calculated by summing up the resistance values of each component.
In this case, the total resistance (R_total) can be calculated by adding the individual resistances (R1, R2, and R3):
R_total = R1 + R2 + R3
R1 = 10Ω
R2 = 15Ω
R3 = 20Ω
Plugging in the values:
R_total = 10Ω + 15Ω + 20Ω
R_total = 45Ω
Therefore, the total resistance of the series circuit with three resistors of 10Ω, 15Ω, and 20Ω connected in series is 45Ω.
To calculate the total resistance of a series circuit, you simply add up the individual resistances. In this case, the three resistors are connected in series.
Total resistance (R_total) = R1 + R2 + R3
Given resistances:
R1 = 10Ω
R2 = 15Ω
R3 = 20Ω
Plugging in the values:
R_total = 10Ω + 15Ω + 20Ω
R_total = 45Ω
Therefore, the total resistance of the series circuit with resistors of 10Ω, 15Ω, and 20Ω is 45Ω.
