Basic Math

If three resistors with resistance of R1, R2, R3 are wired inparralle, their combined combined resitance R is given by thefollowing formula:

1/R= 1/R1 + 1/R2 +1/R3

The design of a voltmeter requires that the resitance R2 be 80ohms greater than the restance of R1, that the restance of R3 be 5ohms greater than R1, and that their combined restance be 10 ohms.Find the value of each resistance.

R1=________ohms

R2=________ohms

R3=________ohms
