To recharge a 12 V battery, a battery charger

must move 2.7 × 105 C of charge from the
negative terminal to the positive terminal.
How much work is done by the battery
charger?
Answer in units of J

Well, let me think. Recharging a battery sounds like a shocking experience! To calculate the work done by the battery charger, we can use the equation:

Work = charge × electric potential difference

Given that the charge moved is 2.7 × 10^5 C and the electric potential difference is 12 V, we can plug in the values:

Work = (2.7 × 10^5 C) × (12 V)

Now let's do some math. *Calculating in progress*

The work done by the battery charger is approximately 3.24 × 10^6 J.

Wow, that's some electrifying work! Just don't zap yourself in the process!

To calculate the work done by the battery charger, we can use the formula:

Work (W) = Charge (Q) x Voltage (V)

Given:
Charge (Q) = 2.7 × 10^5 C
Voltage (V) = 12 V

Substituting the given values into the formula:

W = (2.7 × 10^5 C) x (12 V)

W = 3.24 × 10^6 J

Therefore, the work done by the battery charger is 3.24 × 10^6 J.

To find the amount of work done by the battery charger, we need to use the formula:

work = charge x voltage

In this case, the charge is given as 2.7 × 10^5 C and the voltage is 12 V.

So the work done by the battery charger is:

work = 2.7 × 10^5 C x 12 V

To calculate this, simply multiply the charge and the voltage:

work = 3.24 × 10^6 J

Therefore, the amount of work done by the battery charger is 3.24 × 10^6 Joules.

W =qU = 12•2.7•10^5 =3.24•10^6 J
