Question

In the given circuit diagram calculate
Effective resistance Current in the circuit
​

Answer 1

Answer:

Given,

Two resistors in series. One of 5 ohm and theother of 25 ohm.

These both resistors are parallel to other pair of resistors which are too connected in series.

The other pair of resistors are of the measure 10 ohm and 20 ohm.

So, firstly Finding the total resistance in pair 1 of the resistors = 5 + 25 = 30 ohm.

And the total resistance in pair 2 of the resistors = 10 + 20 = 30 ohm.

Now, Finding the total parallel resistance (which will be also the net total resistance of the circuit) = 1/Rp = 1/30 + 1/30 = 2/30 = 1/15.

Hence, Total resistance = 15 ohm.

Formulas:-

• R(series) = R1 + R2 + .... + Rn

• 1/R(parallel) = 1/R1 + 1/R2 .... 1/Rn
