Question

the total Resistance needed in a given circuit is 50 ohm a student has three resistors of 3 ohm 6 ohms and 48 ohms available with the how should we connect these resistors.

Answer 1

Use one 3 ohm resistor and one 6 ohm resistor in paralel

Step-by-step explanation:

The equation to solve two resistor in paralel:

`R=({(1)/(R1)+(1)/(R2) } )^(-1)`

For the case of only two resistor:

`R=(R1*R2)/(R1+R2)`

Doing this for the 3 and the 6 ohm resistor plus the 48 ohm:

`R=(3*6)/(3+6)+48=50`
