What is the current in a parallel circuit which has two resistors (17.2 ohms and 22.4 ohms) and a power source of 6.0 volts?

Answers

We need to first find an equivalent resistance across the parallel circuit. that is found by the following equation
1/R1 + 1/R2 + ... = 1/Re
So...
1/17.2 + 1/22.4 = 1/Re
0.1021 = 1/Re
Re = 9.792 Ohms

Now use the Voltage equation V = IR
6 = I * 9.792
I = 6/9.792 = 0.613 Amps (or the current)

Answer : The current in a parallel circuit is, 0.6 A

Solution : Given,

Resistance, R_1 = 17.2 ohm

Resistance, R_2 = 22.4 ohm

Voltage = 6.0 V

First we have to calculate the total resistance in a circuit.

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}$

Now put all the given values in this expression, we get the total resistance in a circuit.

$\frac{1}{R}=\frac{1}{17.2}+\frac{1}{22.4}$

$R=9.7\Omega$

Now we have to calculate the current flowing in a parallel circuit.

Using ohm's law :

$V=I\times R$

where,

V = voltage

R = resistance

I = current

Now put all the given values in this formula, we get

$6.0V=I\times 9.7\Omega$

I=0.6A

Therefore, the current in a parallel circuit is, 0.6 A
