Are there circuit solvers?

Are there circuit solvers?

Circuit Solver doesn’t compare to their raw power but it is optimized to run on mobile devices which makes it both portable and easily accessible to anyone in need of circuit solutions.

How do I know what resistor I need?

We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/. 010=860 ohms. To use several LEDs in parallel, sum the current values.

How do you find the resistance value of a circuit?

Determine the resistance and the watts to be dissipated by the resistor. Determine the proper “Watt Size” (physical size) as controlled by watts, volts, permissible temperatures, mounting conditions and circuit conditions. Choose the most suitable kind of unit, including type, terminals and mounting.

What is the total resistance of resistors in series?

The total resistance of resistors in series is simply the sum of the resistances of each resistor. Refer to the equation below for clarification:

How to calculate the equivalent resistance of a circuit?

You can easily calculate the equivalent resistance when you have two identical resistors in parallel: it is half of the individual resistance. This is handy when you need a specific resistance value and don’t have an appropriate part readily available.

How do you find the value of a resistor in series?

When you have only two resistors in parallel: REQ = R1 × R2 R1 + R2 R E Q = R 1 × R 2 R 1 + R 2 Resistors in series are equivalent to one resistor whose resistance is the sum of each individual resistor.

What is a parallel resistive circuit?

By definition, a parallel resistive circuit is one where the resistors have parallel connections or they share the same nodes or points of connection. Also, this type of circuit has more than just one path connected to a single voltage source.
