by using Kirchoffs law
from loop 1
from loop 2
By solving both the equations we get , and
so the current in left branch = 1.042732A and is directed downwards.
current in the middle branch = 0.601988A and is directed downwards
current in the right branch = 1.64472A and is directed upwards.
b)
Energy delivered by 4.0V battery
negative sign is because the current is changing the battery instead of discharging from the battery.
Energy delivered by 16.0V battery
c)
Energy delivered to
Energy delivered to
Energy delivered to
Energy delivered to
Energy delivered to
d) In the operation of the circuit the some energy is used in charging the 4V battery which is transforming from electric to chemical energy. and remaining energy is transformed in to heat energy at the resistors.
e)The total enrgy stored in the internal energy of the resistors = 809.5961+184.8187+36.9637+827.7617+579.4332 = 2483.5734J = 2.4835734KJ
