Question

3. In the circuit diagram, calculate:
(a) effective resistance
(b) potential difference between points A and B and
points B and C
(c) current through branch AC and PQ​

Answer 1

Answer:

• Effective Resistance = 2 ohms.
• Potential Difference between A and B = 2 volts
• Potential Difference between B and C = 4 volts
• Current through Branch AC = 1 amp
• Current through Branch PQ = 2 amp

Explanation:

Resistance (R)

Current (I)

Potential Difference (V)

Effective Resistance = R

For the series AB and BC

$r(ac) = r(ab) + r(bc)$

$2 \: ohms + 4 \: ohms = 6 \: ohms$

For the pareller AC and PQ

$\frac{1}{r} = \frac{1}{r(ac)} + \frac{1}{r(pq)}$

$\frac{1}{r} = ( \frac{1}{6} + \frac{1}{3} ) = \frac{1}{2} \\ r = 2$

R = 2 ohms.

Remaining explanation will be given later since a little busy
