Question

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

A. 900 watts
B. 6.3 watts
C. 68,000 watts
D. 11,000 watts
E. 470 watts

Answer 1

A.900 watts That would be your correct answer 

Answer 2

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=(V^2)/(R)`

In this case, we use relation (1)

`P=12\ V* 75\ A`

`P=900\ W`

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

Hence, this is the required solution.
