3 resistors having the same resistance value are wired in parallel, how does the equivalent resistance compare to the resistance value of a single resistor?

1) The equivalent resistance is thrice the value of a single resistor.

2) The equivalent resistance is the same as the value of a single resistor.

3) The equivalent resistance is one third of the value of a single resistor.

4) The equivalent resistance is greater than the value of a single resistor.

• Science -

1/R = 1/R1 + 1/R2 + 1/R3
Plug any value into R and calculate it.
