Question

Fuel cells have been developed that can generate a large amount of energy. For example, a hydrogen fuel cell works by combining hydrogen and oxygen gas to produce water and electrical energy. If a fuel cell can generate 10.0 kilowatts of power and the current is 15.8 amps, what is the voltage of the electricity?

a.0.63 volts
b.158volts
c.633 volts
d.158,000 volts
e.5.8 volts

Answer 2

Answer:

633 V

Explanation:

According to the Watt´s law, the power generated by an electronic, is directly proportional to the voltage and the current applied. So we can expressed this relation as:

P=V*I

Where P is power in (W), V is the voltage in (V) and I is the current in (A)

Solving the equation for Voltage

V=P/I

V=(10000 W)/15.8 A

V= 633 V
