What voltage battery would you need to send 2.5A of current through a light bulb of resistance 3.6 ohm

Current flow light bulb = 2.5

Resistance of light bulb = 3.6Ω

We have to find voltage of battery

➠ As per ohm's law, current flow through a conductor is directly proportional to the applied potential difference.

➝ V ∝ I

➝ V = I × R

Where, R is the resistance of conductor.

⇒ V = I × R

⇒ V = 2.5 × 3.6

⇒ V = 9 volt

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
