Current is the flow of charge, and charge is conserved; thus, whatever charge flows into the junction must flow out.

Battery to Resistance: Understanding the Relationship and How it

There is a direct relationship between the battery and resistance in an electronic circuit. The battery supplies power to the circuit, and the resistance determines how much of that power is utilized by the device. Higher resistance in a circuit means that more power is consumed by the resistors and less is available for the device.

6 FAQs about [Battery plus resistor for system circuit]

How do you choose a precharge resistor?

The resistance of the precharge resistor is chosen based on the capacity of the load and the desired precharge time. The precharge surge current reaches 1/e of its initial value after a time of: The precharge resistor needs to dissipate as much energy as the energy stored in the load's input capacitors.

Does a relay need a precharge resistor?

The relay needs to be able to handle the peak of the inrush current; but, since the average current is low, and the breaking current is nearly zero, the current rating of the relay is not critical. The resistance of the precharge resistor is chosen based on the capacity of the load and the desired precharge time.

Why is a sense resistor important?

The sense resistor and how it is connected to the data acquisition system are critical design decisions. The sense resistor may see changes in temperature that are much larger than the ambient variations of the battery pack due to power dissi-pation in the resistor.

What happens if a sense resistor is connected to a PCB etch resistor?

If the sense resistor is connected in such a manner as to include some of the PCB etch resistance in the actual sense resistance seen by the measurement circuitry, the effective resistance is increased.

Where is the precharge resistor located?

In the typical precharge circuit, the precharge resistor is on the positive terminal of the battery, though it could just as easily be on the negative terminal. While you are free to use any designators you wish, the ones in this schematic (R1, K2, K2 and K3) appear to be industry standard, so you are encouraged to use them as well.

What is a series resistor used for?

Series resistors may be used to limit the peak current flow. It is noteworthy that 15 kV may arc across the body of some small resistors, reducing or eliminating their effectiveness for limiting current flow and for decoupling.
