Question

In a given circuit, the supplied voltage is 1.5 volts. One resistor is 3 ohms and the other is 2 ohms. Use Ohm's law to determine the current in the circuit.

0.3 amps
1.5 amps
7.5 amps
3.3 amps

Answer 1

0.3

Explanation:

The equation you use is I=
`(V)/(R)`

V=volts

R=ohms

I=amps

You add up the ohms since there are more than one

3+2=5

so 5 ohms

the volts are 1.5

Plug in the numbers:

I=
`(1.5)/(5)`

Solve it-

1.5 divided by 5 equals 0.3

Sooooooo...

The answer is: 0.3

Answer 2

Ohm's law = V =
`(I)/(R)`
So to apply for this values in the formula we have to find total resistance in the cuircuit.
So,
`R_(1) + R_(2)` = total resistance
3 + 2 = 5 ohms
Now, lets plug in the equations
1.5 =
`(I)/(5)` { multiplying both sides by 5 }
5 * 1.5 = I
7.5 = I

So correct option is C
I = 7.5 amps
