Question

A set of three resistors are set up in parallel. The resistor values are R1 = 3.0 Ohms, R2 = 11.0 Ohms, and R3 = 7.5 Ohms.

What is the total resistance of this circuit?
a
1.79 Ohms
b
0.60 Ohms
c
1.12 Ohms
d
2.97 Ohms

Answer 1

A) 1.79ohms

Step-by-step explanation:

Total resistance of resistors in parallel is given by ;

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

Put in the values and make R the subject
