Question

Two 120 Ω resistors are connected in parallel across a supply voltage of 10 VDC. What's the current in this circuit?

Answer 1

As we know that here two 120 ohm resistors are connected in parallel with the battery of voltage 10 V DC

now here we will use Ohm's law

$V = i R$

so here we can use above equation to find the current in each resistor

$10 = i \times 120$

$i = \frac{10}{120}$

$i = 0.0833 A$

so here this will be the current flow through each resistor

now the total current through both resistors will be given as

$i_{total} = 0.0833 + 0.0833 = 0.167 A$

Answer 2

Answer:

Current in the circuit = 0.167 A

Explanation:

We have the equation, Voltage, V = Current x Resistance.

                     V = IR

Resistance in parallel connection is given by

     $\frac{1}{R}=\frac{1}{120}+\frac{1}{120}\\\\R=60\Omega$

Voltage = 10 V

Substituting

               10 = I x 60

               I = 0.167 A

Current in the circuit = 0.167 A
