Question 47

An electric scooter's battery is being charged.

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

[1]

The battery of the electric scooter can store $3.24 \times 10^6\text{ J}$ of energy. The charger has a power output of $W180\text{ W}$ . Calculate the time taken, in seconds, to fully charge the battery from zero.

[2]

State the equation that links current ( $I$ ), potential difference ( $V$ ), and resistance ( $R$ ).

[1]

When the scooter is running, the potential difference across its electric motor is $V36\text{ V}$ . There is a current of $A8.0\text{ A}$ in the motor. Calculate the resistance of the motor.
