What is a current divider circuit and how does it function?
1 Answer
As of my last update in September 2021, a current divider circuit is a simple electronic circuit used to divide a single current into multiple branches. It allows you to distribute a current from a single source among different resistive loads, creating separate current paths for each load. The current divider circuit is based on Ohm's Law, which states that the current passing through a resistor is directly proportional to the voltage across it and inversely proportional to its resistance.
The basic principle of a current divider circuit is that the current flowing through each branch is determined by the ratio of the resistance of that branch to the total resistance of all the branches. Here's how it functions:
Circuit Configuration: The current divider circuit typically consists of a single voltage source (such as a battery or power supply) connected in parallel to multiple resistors (loads).
Applying Ohm's Law: Let's assume you have a current source (I_total) connected to the current divider circuit, and you want to find the currents flowing through each resistor (I1, I2, I3, and so on).
Calculating Individual Currents: The current flowing through each resistor can be calculated using the formula:
I1 = I_total * (R_total / R1)
I2 = I_total * (R_total / R2)
I3 = I_total * (R_total / R3)
...
Where:
I1, I2, I3, ... are the currents through each resistor.
R1, R2, R3, ... are the resistances of each resistor.
R_total is the sum of all the resistances in the circuit.
Distributing Current: The calculated currents (I1, I2, I3, ...) represent the amount of current flowing through each resistor, effectively dividing the total current (I_total) into different branches.
It's important to note that in a current divider circuit, the voltage across each resistor may be different, as it depends on the resistance of each branch. The current is what gets divided based on the resistances. Also, keep in mind that the sum of all the individual currents (I1 + I2 + I3 + ...) will always equal the total current (I_total) to satisfy the law of conservation of charge.
The current divider circuit is commonly used in electronics and electrical engineering to power multiple components or loads from a single current source while ensuring that each component receives the appropriate amount of current.
