Answer:

0.615 Watts of power are used by the circuit

Step-by-step explanation:

the formula for Electric power is

P = V*I

where P= power used by the circuit [watts], V= tension of the battery [V=volts], I=circuit current [A=amperes].

therefore

P= V*I= 1.5 V * 410 mA * (1 A / 1000 mA) = 0.615 W

P= 0.615 Watts
