All answers in ohms
series 55 parallel 5
series 10 parallel 2.4
series 29 parallel 2
A series circuit has only one current path and the potential has to be divided between the components. As a result the current is low and therefore by Ohm’s law the resistance is high.
A parallel circuit has one current path for each resistor and each has the same. As a result the current is high and therefore by Ohm’s law the resistance is low.
