it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
The equivalent resistance will be 0.75 ohms.
This one can be tricky, but only because we have a limited ability to write equations here in this frame. The basic formula (or at least one of them) for...
