Question

calculate the total resistence in the given electric circuit below

Answer 1

Answer:

V=6V

R1=2ohms

R2=3ohms

(a) Resistors are connected in parallel.

(b) p.d. across each resistor is same and is equal to 6V.

(c) 2 ohms resistance have bigger share of current because of its lower resistance.

(d) Effective resistance = R

1/R=1/2+1/3

1/R=5/6

R=1.2ohms

(e) Current flowing through battery , 

I=RV=1.26=5amps 

Answer 2

Explanation:

here the circuit has both parallel and series resistor

$\frac{1}{ {r}^{p} } = \frac{1}{10} + \frac{1}{10} \\ \\ = \frac{1 + 1}{10} \\ \\ = \frac{2}{10} \\ \\ \frac{1}{ {r}^{p} } = \frac{1}{5} \\ \: \\ {r}^{p} = 5 \: ohms$

${r}^{s} = (6 + 16 + 5) \: ohms \\ \\ {r}^{s} = 25 \: ohms$

the total resistance in the circuit is abot 25 ohms
