Introduction

In this article, we will explore the concept of calculating total current and power in a series circuit. A series circuit is a type of electrical circuit where components are connected one after the other, and the current flows through each component in sequence. The total current and power in a series circuit can be calculated using Ohm's law and the formula for power.

Understanding Series Circuits

A series circuit consists of multiple components connected in a single loop. The current flows through each component in sequence, and the voltage across each component is the same. The total resistance of the circuit is the sum of the individual resistances.

Calculating Total Resistance

To calculate the total resistance of a series circuit, we add the individual resistances together. In this case, we have three resistors with values of $ R_1 = 2 , M\Omega $, $ R_2 = 57 , M\Omega $, and $ R_3 = 120 , M\Omega $. The total resistance is calculated as follows:

R_total = R1 + R2 + R3
R_total = 2e6 + 57e6 + 120e6
R_total = 179e6

Calculating Total Current

The total current in a series circuit can be calculated using Ohm's law, which states that current is equal to voltage divided by resistance. In this case, the supply voltage is $ 25 , kV $, and the total resistance is $ 179 , M\Omega $. The total current is calculated as follows:

I_total = V_supply / R_total
I_total = 25e3 / 179e6
I_total = 1.4e-4

Calculating Total Power

The total power in a series circuit can be calculated using the formula $ P = I^2R $. In this case, the total current is $ 1.4 , \mu A $, and the total resistance is $ 179 , M\Omega $. The total power is calculated as follows:

P_total = I_total^2 * R_total
P_total = (1.4e-6)^2 * 179e6
P_total = 3.96e-3

Conclusion

In this article, we calculated the total current and power in a series circuit with the following parameters: $ R_1 = 2 , M\Omega $, $ R_2 = 57 , M\Omega $, $ R_3 = 120 , M\Omega $, and $ V_supply = 25 , kV $. The total resistance was calculated as $ 179 , M\Omega $, and the total current was calculated as $ 1.4 , \mu A $. The total power was calculated as $ 3.96 , mW $.

Discussion

The calculation of total current and power in a series circuit is an important concept in physics and electrical engineering. Understanding how to calculate these values is crucial for designing and analyzing electrical circuits.

Real-World Applications

The calculation of total current and power in a series circuit has many real-world applications. For example, in the design of electrical circuits for electronic devices, it is essential to calculate the total current and power to ensure that the circuit can handle the required load.

Limitations

The calculation of total current and power in a series circuit assumes that the circuit is linear and that the components are ideal. In reality, circuits can be nonlinear, and components can have imperfections that affect the calculation of total current and power.

Future Work

In future work, we can explore more complex circuits and calculate the total current and power in more complex scenarios. We can also investigate the effects of nonlinearity and component imperfections on the calculation of total current and power.
