Question

15.0Ω 7.5 Ω Current 0.40 Α) 8.0V 15.0 Ω

Design a Circuit using only 2 resistors of 15 Ohm and 1 resistor of 75 Ohm.

1. Using all three resistors, design a circuit that will draw ~320 mW from power supply when connected across 8.0 V. Determine theoretically the power consumption of each individual resistor in the circuit you have designed.

2. Annotated potential vs path graph with accompanying Kirchhoff’s Laws written as algebraic statements.

Answer 1

1.) in circuit 0.40 Ampere current flowing applied voltage Power supply to given 8 volt circuito 8x0.40 •320 W 320 mw Hence this circuit is accurate design decanding to gives information. Power across first is & Resistor = IR (0.4 x 15 こ 2.4 W Porter equivalent Resistance of parallel Gmbinations = ㅗ ㅗ 7.5 R +L 15 2 TL N of 15 R = 15:52 3 vo Voltage across parallel Combination IR 0.485 2 volt,

Power across Ish I v2 R 15 -.2667 Wor 266.7 mw 2 2 Power across 7.5h = v² R 11 7.5 = 0.533w or 533 mW 2.) Equivalent Resistances of parallel combination is sch Now our circuit becomes sur apply KVL on ABCD loop D -8 +15I + ST = 0 I 81 201 m = 8 = B А . Isr 1 0.41 Which is same as given
