The equivalent resistance is thrice the value of a single resistor.
The equivalent resistance is the same as the value of a single resistor.
The equivalent resistance is one third the value of a single resistor.
The equivalent resistance is greater than the value of a single resistor.
Three resistors having the same resistance value are wired in parallel. How does the equivalent resistance compare to the resistance value of a single resistor?

The current now has three choices for where to go, but the voltage is the same for all three.
itotal = V/R + V/r + V/R
itotal = 3 V/R = V/(R/3)
which is the voltage divided by the equivalent resistance, R/3
itotal = V/R + V/r + V/R
itotal = 3 V/R = V/(R/3)
which is the voltage divided by the equivalent resistance, R/3
if resistors are parallel, then equivalent resistance R=1/(1/R1 + 1/R2 + 1/R3); all
R are the same => R = R/3 => R/R1 = (R/3)/R <=> 1/3
R are the same => R = R/3 => R/R1 = (R/3)/R <=> 1/3
