Question

The circuit diagram given shows the combination of r1 r2 r3 : FIND (1) total resistance of the circuit (2) total current flowing in the circuit (3) the potential difference across r1 ​

Answer 1

$\red{hola}$

Solution : (i) Total resistance of two resistors that are connected in parallel is 1/R’ = 1/3+1/6 1/R’ = 3/6 R’ = 2ohms Total resistance of the circuit = 2+4ohms = 6ohms (ii) Total current flowing through the circuit=V/total resistance I = 12/6 = 2amps (iii) Potential difference across R1=R1 x I = 4 x 2 = 8V.Read more on Sarthaks.com - https://www.sarthaks.com/127410/the-circuit-diagram-given-below-shows-the-combination-of-three-resistors-r1-r2-and-r3

Answer 2

Answer:

Total resistance = 6 ohm

Current = 2 A

Potential difference across R1 = 8 V
