Given the expression:
And:
R1 = 2 ohms;
R2 = 3 ohms;
R3 = 3 ohms.
Substitute the values to find R.
Take the least common denominator of 2, 3, 3.
The multiples of 2: 2, 4, 6, 8 ...
Multiples of 3: 3, 6, 9 ...
So, the least common denominator is 6. Then,
To divide 2 fractions, flip the second fraction, then multiply. So,
Answer: The total resistance is 6/7.
