Total clockwise moment is greater than total anticlockwise moment

All moments are zero

Total clockwise moment equals total anticlockwise moment

Force equals distance

Effort divided by load

Load times effort

Effort times distance

Load divided by effort

Because friction wastes some of the input energy

Because the load is always larger than the effort

Because the velocity ratio is always one

Because moments cancel out

It is smaller than the smaller single resistor

It is exactly the sum of the two single resistance values added together

It is always equal to the value of the larger single resistor on its own

It is always zero ohms no matter what the resistors are
