Question

Part A

For the circuit shown in the figure(Figure 1) find the current through each resistor.

Part B

For the circuit shown in the figure find the potential difference across each resistor.

Answer 1

Resistance of the middle branch

6+ 8*24/32 = 12 ohm

Ressitance of the whole circuit = 4 + 12*24/36 = 12 ohm

Net current in hte circuit = 24/12 = 2 A

Part B

voltage across 4 ohm = 2*4 = 8 V (ans)

current in through 6 ohm ressitance in the middle branch = 2*24/36 = 1.333 A

voltage across 6 ohm = 1.3333*6 = 8 V (ans)

voltage across 24 ohm(right most brnach)= 24 *(2-1.333 ) = 16 V (ans)

voltage across 8 ohm and 24 (middle branch) ohm = 16- 8 = 8 V (ans)

Part A

current through 4 ohm = 2 A(ans)

current through 6 ohm = 1.333 A(ans)

current through 8 ohm = 24*1.3333/32 = 1 A (ans)

current throguh 24 ohm (middle) = 1.3333- 1 = 0.3333 A (ans)

current through 24 ohm (right most branch) = 2-1.333 = 0.667 A (ans)
