Answer 2

To calculate the values of current (i1 and i2), we can use Ohm's law and apply the principles of series and parallel resistors.

Let's start with calculating i1:

Given: R1 = 5 Ω R2 = 3 Ω u1 = 2 V

We can find the total resistance (RT) using the formula for resistors in series:

RT = R1 + R2 = 5 Ω + 3 Ω = 8 Ω

Now, we can calculate the current flowing through the circuit using Ohm's law:

i1 = u1 / RT = 2 V / 8 Ω = 0.25 A (or 250 mA)

Therefore, the value of i1 is 0.25 A or 250 mA.

Moving on to i2:

Given: u2 = 3 V

Since R2 is in parallel with the rest of the circuit, we can find its effective resistance (Rp) using the formula for resistors in parallel:

1/Rp = 1/R1 + 1/R2 = 1/5 Ω + 1/3 Ω = (3 + 5) / (5 * 3) Ω = 8 / 15 Ω = 0.533 Ω (approximately)

Now, we can calculate the current flowing through R2 using Ohm's law:

i2 = u2 / R2 = 3 V / 3 Ω = 1 A

Therefore, the value of i2 is 1 A.
