Testing low current in PCBAs during the in-circuit test stage requires complex test planning and incorporation of external test instruments. Learn how to integrate source measure units into the in-circuit testers to simplify the testing process.
However, when the internal resistance is not enough to measure larger currents, an external configuration is needed. To measure larger currents, you can place a precision resistor called a shunt in parallel with the meter. Most of the current flows through the shunt, and only a small fraction...
How do you find the current in a resistor in a parallel circuit? Resistance in Parallel: Two resistances are said to be in parallel if the one terminal of a resistor is connected to the one terminal of the other resistor, and a similar connection is made with their other terminal...
in the circuit must equal the total power applied by the source(s). Therefore, an interesting rule for total circuit power versus individual component power is that it is additive for any circuit configuration: series (Table 2), parallel (Table 3), or any combination of series and parallel....
In this post we systematically discuss how to connect diodes in parallel for getting upgrading the overall current specifications of the assembly. This requires special circuit arrangement to ensure uniform current distribution between the devices. ...

Electromagnetic Force: Electromagnetic force between parallel conductors during a short circuit is crucial for understanding mechanical stress in circuit breakers. How to Calculate Short Circuit Current of Circuit Breaker: Calculating the short circuit current involves specific formulas and understanding material...
In this step we will begin the assembly of our parallel circuit. This is the most difficult part of the procedure, so if you are not successful reread the instructions and compare your circuit to the ones in the pictures. None of the components can be damaged if you put a wire in the...
How to Calculate the Emitter Current Limiting Resistor in Parallel BJTs It is actually very simple, and could be calculated using Ohm's Law: R = V/I, Where V is the supply voltage used in the circuit, and "I" could be 70% of the transistor's maximum current handling capacity. ...
