Question

FIND ;
1The resistance between the points P and Q is
2. the current flowing in the circuit is
3.The potential difference between the points A and B is

Answer 1

Answer:

1) $\frac{26}{7}$Ohm

2) $\frac{21}{26}$A

3) $\frac{21}{26}$V

Explanation:

1)

R(PA) = 1 Ohm

R(AB) = 1 Ohm

R(BQ) = 12/7 Ohm

R(PQ) = R(PA) + R(AB) + R(BQ)  [As they are in series]

R(PQ) = $\frac{26}{7}$

2)

$V = IR\\3 = I * \frac{26}{7}\\ I = \frac{ 21}{26}$

3)

$V = IR\\V = \frac{21}{26} * 1\\V = \frac{21}{26}$
