What is the current in the bulb it has resistance ${15}{\Omega}$?

The formula for current is I = V/R

Thus one can only calculate the ampere if one has the voltage and resistance. The information provided is not sufficient.

0 Ampere, Current doesn't flow in a closed-loop circuit when there is no voltage! Potential difference excites electrons and thus creates currents in a closed-loop circuit.

1 0

interestingly though they haven't specified if it a closed-loop or not and theoretical or formula wise current is inversely proportional to the resistance thus I= 1/15 R????? Clarify Mr. Edzai
