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

Ohm's law = V = $\frac{I}{R}$
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 = $\frac{I}{5}$ { multiplying both sides by 5 }
5 * 1.5 = I
7.5 = I

So correct option is C
I = 7.5 amps

Answer 2

Answer:

0.3

Step-by-step explanation:

The equation you use is I=$\frac{V}{R}$

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=$\frac{1.5}{5}$

Solve it-

1.5 divided by 5 equals 0.3

Sooooooo...

The answer is: 0.3
