Answer:
0.5 Amperes
Explanation:
Information that we have:
Power:
Voltage:
and we use the equation that relates this two quantities to the Current (I):
where I is the curent, P is the Power and V is the Voltage.
we substitute the values given for the Power and the Voltage to find the current:
the Current running into the bulb is 0.5 Amperes
