A bird is in contact with a high voltage line. The voltage between the ground and the wire is 4,800 V. The voltage between the bird and the ground is ____ V.
What is 4,800 Volts.
In a fan's circuit, the battery acts as a voltage source. When the circuit is closed by the switch, an electric field is established in the wire. As a result of the field, electrons in the wire experience a force that causes them to drift through the wire, producing a _______.Electrons move toward the _____ terminal of the battery.
What is current and positive.
A current-carrying conductor produces a magnetic field. This happens because, when current is flowing, many charged particles are moving in the (same/opposite) direction.
What is the same.
What is the charge of a neutron?
What is no charge.
