Can electrical equipments draw currents or they allow too flow current through them?
an over loaded ckt will ''draw current''
Current Draw is just a term for the amount of surrent flowing through an appliance. Current does not flow by itself. Current flow is the result of an electrical pressure, voltage. Just as water does not flow through a pipe unless a source of pressure is applied. Then the flow of water (current) will be proportionate to the pressure(voltage) for a given csa pipe (resistance).
Electrical equipment will draw current from a source when it is switched on. Closing the switch allows the current to flow because the voltage is able to supply the current.
I wondered the same thing when I was learning about electricity. Neither, and both is the answer. Voltaic pressure forces the flow, IF there is a circuit to flow through. And if there is a circuit, that circuit will have some resistance, which will 'fight' to resist that flow. Current is 'drawn' only from the viewpoint of the electrician in the field, who sees current flowing only when he hooks up a load and completes a circuit.
