Question 13

85%

An electric scooter is charged using a home charger, and its battery stores energy to run its motor.

Write down the equation that links energy transferred ( $E$ ), power ( $P$ ), and time ( $t$ ).

[1]

The battery pack of the electric scooter can store $J5\,760\,000\text{ J}$ of energy. The charger has a power output of $W800\text{ W}$ . Calculate the time taken to fully recharge the battery pack from empty.

[2]

When the scooter is running, the potential difference across its motor is $V36\text{ V}$ , and there is a current of $A12\text{ A}$ flowing through it. Calculate the resistance of the motor.
