Total resistance in a given circuit.Depends upon the circuit. For series: R=R1+R2+R3…. and so onFor parallel: 1/R=1/R1 + 1/R2 +1/R3… And so on.
equivalent resistance is the algebraic sum of the resistance the current through the circuit can be found from ohm\’s law and is equal to the voltage divided by the equivalent resistance
Havled of resistance

More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating \’total\’ resistance, which we calculate differently for series and parallel circuits. In a series circuit, the different components are connected in a single, continuous loop
