Question

Given a DC battery of voltage, V = 10.0 V connected to a resistor R = 2.00 Ohms. What is the current coming out of the battery? A)48.2 A B)7.67 A C)9.65 A D)23.4 A E)5.00 A

Answer 1

Given:

The voltage of the battery, V=10.0 V

The resistor of the resistance, R=2.00 Ω

To find:

The current coming out of the battery.

Explanation:

From Ohm's law, the voltage across a circuit is directly proportional to the current through the circuit.

Thus, the voltage of the battery is given by,

$V=IR$

Where I is the current coming out of the battery.

On substituting the known values,

$\begin{gathered} 10.0=I\times2.00 \\ \Rightarrow I=\frac{10.0}{2.00} \\ =5.00\text{ A} \end{gathered}$

Final answer:

The current coming out of the battery is 5.00 A.

Thus the correct answer is option E.
