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

Current in the circuit = 0.167 A

Step-by-step explanation:

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

V = IR

Resistance in parallel connection is given by

`(1)/(R)=(1)/(120)+(1)/(120)\\\\R=60\Omega`

Voltage = 10 V

Substituting

10 = I x 60

I = 0.167 A

Current in the circuit = 0.167 A

Answer 2

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 * 120`

`i = (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`
