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.
