A hydrogen 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 i
s the power supplied to the motor by the fuel cell?
1 answer:
<span>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
