The relation between Power, Current and Voltage is given as:
P = V i
where P is Power in Watts,
V is Voltage in Volts,
and i is Current in Ampere.
We are given:
Power = 150 milliwatts = 0.15 Watts
(as 1 milliwatt = 0.001 Watts)
Voltage = 1.5 volts
and we need to find the current.
Hence using above equation:
P = V i
i = [tex]\frac{P}{V}[/tex]
i = [tex]\frac{0.15}{1.5}[/tex]
i= 0.1 Ampere
Answer:
The current used is 0.1 Ampere
