Answer:
The value of currents are ,
and
.
Step-by-step explanation:
The Ohm's law states that
it is given that the V₁=3V and V₂=4V.
In a parallel circuit:
- Voltage is same in each component
- Sum of the currents equals to the total current that flows.
.... (1)
Equation for first loop is,
..... (2)
Equation for second loop is,
..... (3)
On solving (1), (2) and (3) we get
Therefore the value of currents are ,
and
.
