Three resistors are set up in a series. The values are R1=2 Ohms, R2= 13 Ohms, and R3= 5.5 Ohms. What’s the total resistance of this circuit?

I think it’s 20.5 R

R = R1+R2+R3 = 2+13+5.5 =

To find the total resistance of a series circuit, you simply add up the resistances of each individual resistor. In this case, the total resistance (RTotal) is equal to the sum of R1, R2, and R3.

RTotal = R1 + R2 + R3

Plug in the given values:

RTotal = 2 Ohms + 13 Ohms + 5.5 Ohms

RTotal = 20.5 Ohms

Therefore, the total resistance of this circuit is 20.5 Ohms.
