Ahydrogen fuel cell supplies power for a small motor. the fuel cell delivers a current of 0.5 a and a voltage of 0.43 v. what is the power supplied to the motor by the fuel cell?

the power supplied to the motor by the fuel cell is 0.31 watts.

The current , I is 0.5 A.
Voltage, V is 0.43 V

From ohm's law: V = IR 
Thus, R = 0.43/0.5 = 0.86Ω

Now, Power = R
                     = 0.5 ×0.5×0.86
                     = 0.215 W

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

B) raising the temperature and reducing the volume of the gas.|-/
