Question

A 10 ohms resistor is powered by a 5-V battery. The current flowing
through the source is:

Answer 1

• Resistance=R=10ohm
• Voltage=V=5V
• Current=I

Applying ohm's law

$\\ \sf\longmapsto \dfrac{V}{I}=R$

$\\ \sf\longmapsto I=\dfrac{V}{R}$

$\\ \sf\longmapsto I=\dfrac{5}{10}$

$\\ \sf\longmapsto I=0.5A$
