Question

Calculate the power produced by a 12 V battery charger if it delivers:A. 10 A in the fast charge modeB. 2 A in trickle charge mode

Answer 1

The power produced by a 12 V battery charger is 120 W in the fast charge mode and 24 W in the trickle charge mode.

Step-by-step explanation:

To calculate the power produced by a battery charger, you can use the formula P = IV, where P is power, I is current, and V is voltage.

For the fast charge mode with a current of 10 A:

1. Power (P) = Current (I) × Voltage (V)
2. P = 10 A × 12 V
3. P = 120 W

For the trickle charge mode with a current of 2 A:

1. Power (P) = Current (I) × Voltage (V)
2. P = 2 A × 12 V
3. P = 24 W

Answer 2

The electric power (P) produced by an electric current (I) passing through a voltage (V) is given by the equation:

`P=VI`

If the battery charger works with a voltage of 12V, replace V = 12V into the equation, as well as the corresponding values for the electric current to find the power produced in each case.

A) I = 10A

Replace V=12V and I=10A to find the power produced in the fast charge mode:

`P=(12V)(10A)=120W`

B) Replace V=12V and I=2A to find the power produced in the trickle charge mode:

`P=(12V)(2A)=24W`

Therefore, the power produced by a 12V battery charger is equal to 120 Watts when it delivers 10A in fast charge mode, and 24 Watts when it delivers 2A in trickle charge mode.
