A car battery can deliver up to 75 amps of current at a voltage of 12 volts. How much power is this?

A900 watts
B6.3 watts
C68,000 watts
D11,000 watts
E470 watts

Verified Answer :

A.900 watts That would be your correct answer

Answer : Power = 900 watts

Explanation :

It is given that,

A car battery can deliver up to 75 amps of current at a voltage of 12 volts. The power delivered is given by the following relation :

\(P=VI\)

or

\(P=I^2R\)

or

\(P=\dfrac{V^2}{R}\)

In this case, we use relation (1)

\(P=12\ V\times 75\ A\)

\(P=900\ W\)

The correct option is (A) " 900 Watts ".

Hence, this is the required solution.
