Question

find voltage across 10 ohm resistor​

Answer 1

Answer:

The voltage across parallel resistors:

Now, i1 = V(supply) / R(equivalent) = 5 /22 = 0.227 amps. ...

Voltage drop across 10 ohm -> Vr1 = 10 * i1 = 10 × 0.227 volts. ...

Now, i2 = i1 * (R3/(R1+R2)) ...

Voltage drop across 20 ohm -> Vr2 = 20 * i2 = 20 × 0.1362 volts. ...

Now, i3 = i1 * (R2/(R1+R2))

Answer 2

The voltage across the $10-ohm$ resistor is:

If we calculate the current in this way, we can apply it to all our calculations.

Ohm's law states that $I = \frac{V}{R}$ is current.

The voltage across the circuit is $12 volts$, and the total resistance is 10 ohms.

The answer is$I = \frac{12}{10} = 1.2 amperes.$

The voltage decreases.

$10 ohm ---> Vr1 = 10 * i1 = 10 * 0.227 volts$

$Vr1 = 2.27 volts \\Now, i2 = i1 * (\frac{R3}{(R1 + R2)} )$

∴ $i2 = 0.1362 A$
