In a circuit, two resistors of 100 ω and 80 ω are connected in parallel. the parallel group is then connected in series with a 100 ω resistor. what's the total resistance of the circuit?

Total Resistance = Ω  (or 144.44 Ω)

Step-by-step explanation:

If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:

If 2 resistors with resistance x and y and connected in series, their total resistance would be:

Total = x + y

Now, the first part, 100 and 80 are in parallel, so according to formula it would be:

Now, this is connected in series with 100, so the grand total would be:

Total Resistance of Circuit =

This is the total resistance of the circuit.

your answer is -9
