Answer
An electric motor is a device that converts electrical energy to mechanical energy. It operates by using the interactions between magnetic fields and current-carrying conductors to produce rotational motion.

Answer
A distinguishing feature of a GS motor is its commutator, which allows for the reversal of current direction in the motor windings, enabling continuous rotation.

Answer
The coil will rotate anti-clockwise when viewed from point O, assuming the current direction and magnetic field are appropriately aligned.

Answer
In a WS-generator, mechanical energy is converted into electrical energy through electromagnetic induction.
Step 5
'n Transformator het 1 500 sekondêre windings en 250 primêre windings. Indien die sekondêre potensiaalverskil (spanning) 240 V is, bereken die primêre potensiaalverskil (spanning).

Answer
Using the transformer equation,
VpVs=NpNs
where
Vs = secondary voltage = 240 V,
Ns = number of secondary windings = 1500,
Np = number of primary windings = 250,
we can rearrange to find Vp:
Vp=Vs⋅NsNp=240⋅1500250=40 V.
Therefore, the primary potential difference is 40 V.
