Dependent Voltage Can Any One Explain For Me How We Get P3 class=

Sagot :

Answer:

Explanation:

Power in the circuit must balance

Voltages about any loop must add to zero

Current through any node must add to zero

p1 has 5V and 8 Amps leaving the + terminal

This means that (5)(8) = 40 W is being supplied by p1 ergo -40W

p2 has 2V and 8 amps entering the + terminal

2(8) = 16 W absorbed by p2

p4 has 3V and 5 amps entering the + terminal

3(5) = 15 W absorbed by p4

Balance of power shows that p3 must absorb

15 + 16 + P3 - 40 = 0

P3 = 9 W absorbed
