Question

What is the electric potential difference of the circuit if the current is 0.1 A?

Answer 1

Given:

The resistance of the resistors, R₁=4 Ω

And R₂=3 Ω

And R₃=5 Ω

The current in the circuit is I=0.1 A

To find:

The potential difference in the circuit.

Step-by-step explanation:

All the resistors are connected in series with the battery. The equivalent resistance of the resistors connected in the series is given by,

`R=R_1+R_2+R_3`

On substituting the known values,

`\begin{gathered} R=4+3+5 \\ =12\text{ }\Omega \end{gathered}`

From Ohm's law, the potential difference of the circuit is directly proportional to the current in the circuit.

Thus,

`V=IR`

On substituting the known values,

`\begin{gathered} V=0.1*12 \\ =1.2\text{ V} \end{gathered}`

Final answer:

The potential
