HEY FRND☺✌✋↪ YOUR ANSWER ⬇⬇
Equivalent Resistance is nothing but the Total resistance in the System being considered.
Suppose, a House wiring system has 5 bulbs each and that are connected in parallel( House wiring is connected in Parallel only , because different appliances in the house have different current ratings 5A, 6A, 10A, 15A etc but same Voltage rating 200 Volts, thus in parallel).
Suppose each bulb has a wattage of 20W, so the current in each parallel wire is i = 20W/200V = 1/10 A.
Each wire of the five wires have a current i = 1/10A and thus a resistance = r = V/i = 2000 ohms.
Each resistor has a resistance around 2000 ohms thus, the equivalent resistance of the parallel system is 400 ohms.
✴⚫↪Remember in the parallel Connections the Equivalent Resistance is even less than the least resistance present in the System and in the Series Connections the Equivalent Resistance is greater than the greatest resistance present in the SYSTEM.
✴⚫↪Had it been a Series Circuit the Resistances would have been added up normally r= r1 + r2 + r3.....though current would have been different and we had to reconsider that circuit.HOPE THIS will HELPS U FRND ☺☺
