Determine the currents in the picture

Mathematics
1 answer:
Evgesh-ka [11]3 years ago
4 0

Answer:

The value of currents are I_1=0A, I_2=1A and I_3=1A.

Step-by-step explanation:

The Ohm's law states that

V=IR

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.

I_2=I_1+I_3                   .... (1)

Equation for first loop is,

V_1=4I_1+3I_2

3=4I_1+3I_2              ..... (2)

Equation for second loop is,

V_2=1I_3+3I_2

4=1I_3+3I_2             ..... (3)

On solving (1), (2) and (3) we get

I_1=0

I_2=1

I_3=1

Therefore the value of currents are I_1=0A, I_2=1A and I_3=1A.

670<br> If a die is rolled 3 times, what is the total number of possible outcomes?
Triss [41]
There is to say, for each first roll, we start out with six possibilities; for each of these, there are six possibilities for the second roll; finally, for each second roll, there are six possibilities for the third. So, 6 cubed. So, 216 is our denominator, i.e., the number of all possible outcomes.

Answer: 216
