For 2 resistors in parallel you can use this formula. Rp = (R1 * R2)/R1 + R2 (only for 2 resistors in parallel) Tags Electroschematics. P. Marian. About P. Marian. I love all about electronics, ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a parallel circuit add up to the supply current.

Necro-comment: I actually do it the other way — the 1k resistors are two 2ks in parallel. Same-same. Report comment. denis says: April 10, 2017 at 11:23 am ...

For resistors in parallel, meanwhile, you use a different method - one that gives you a resistor with an equivalent resistance that's smaller than any of the individual resistors in the branches.

Sense resistors in series with the load can force current sharing between regulators, but using low-side sense elements yields even better results. To improve efficiency in high-power applications ...

Use Ohms law to relate resistance, current and voltage. In National 5 Physics calculate the resistance for combinations of resistors in series and parallel.

Resistors may be connected in parallel with voltage-sense connections made to just one of the resistors, provided the track layout ensures equal distribution of current between all resistors.

Of course, now you have two 40 ohm resistors, but when you put them in parallel you get the 20 ohms you desire. You also used four times the amount of wire, but there’s no free lunch.

Assuming an infinite power supply, you could add 1000 resistors in parallel and the current in that one resistor wouldn't change. IEEE Std. 80 uses a value of 1000 ohms for the human body for touch ...

5 comments on “ Parallel Resistors ” jimfordbroadcom December 10, 2013. Yeah, a handy program to have. I just did the algebra from the parallel resistor formula RP= R1*R2/(R1 + R2) and came up with R1 ...
