Product over sum = product/sum = (r1*r2)/(r1+r2).
= (150 * 6800)/(150+6800)
= 1020000/6950.
= 146.76258993 answer.
= (150 * 6800)/(150+6800)
= 1020000/6950.
= 146.76258993 answer.

This is the rule in parallel circuit that the total resistance of parallel circuit is nearly less than from the smallest resistance in parallel circuit so in these answers nearly value is 146.7 and also from formula given above.

Name suggested product over sum means first product the given values and then sum it now results of both are divided prodect over sum example: two values say R1&R2 the resultant product of sum is R= (R1*R2) / (R1+R2).

Friends,
Parallel resistance R=(R1*R2)/(R1+R2)
where R1, R2 are the two parallel resistors
Hence,
R = (150*6800)/(150+6800) = 146.7.
Parallel resistance R=(R1*R2)/(R1+R2)
where R1, R2 are the two parallel resistors
Hence,
R = (150*6800)/(150+6800) = 146.7.

Formula of product over sum r = (r1 * r2)/(r1 + r2).
r = (150 * 6800)/(150 + 6800),
r = 146.7ohm.
r = (150 * 6800)/(150 + 6800),
r = 146.7ohm.

This rule is sum of the parallel form resistance Rp = r1*r2/r1+r2 150*6800/150+6800 = 147.76.

R = (R1*R2) /(R1+R2).
= 150*6800/150+6800.
= 1020000/6950.
Total = 146.76259.
= 150*6800/150+6800.
= 1020000/6950.
Total = 146.76259.

Formula of: product-over-sum r=(r1*r2)/(r1+r2)
r=(150*6800)/(150+6800)
r=146.7ohm
r=(150*6800)/(150+6800)
r=146.7ohm

product=150*6800=1020000
sum=150+6800=6950
product-over-sum=1020000/6950=146.7
sum=150+6800=6950
product-over-sum=1020000/6950=146.7

sum=150+6800
product=150*6800
therefore
product over sum=1020000/6950
=146.7
product=150*6800
therefore
product over sum=1020000/6950
=146.7
