If two equal resistors are connected in parallel, the equivalent resistance is:
Double the value of a single resistor
Equal to the value of a single resistor
Half the value of a single resistor
Four times the value of a single resistor
解释
With two equal resistors in parallel, the total resistance is half the value of one resistor.
