Moodle Activity Examples

Either a stranded conductor (single-conductor cable) or a combination of conductors insulated from one another (multiple conductor cable). Small sizes are commonly referred to as stranded wire or as cords [4].

A group of wires or ribbons of wiring used to interconnect electronic systems and subsystems [14].

The property of an electrical circuit that opposes changes in voltage [2].

The opposition, expressed in ohms, offered to the flow of an alternating
current by capacitance. The symbol for capacitive reactance is X C [2] [9].

An electrical device capable of storing electrical energy in an electrostatic field [2].

This filter is used on extremely high-voltage, low-current power supplies and
also where the ripple frequency is not critical [7].

A type of single-phase, ac induction motor in which a starting winding
and a capacitor are placed in series to start the motor. The values of XC and R are such that the main-winding and starting-winding currents are nearly 90 degrees apart and the starting torque is produced as in a two-phase motor [5].

A microphone in which sound waves vary the resistance of a pile of carbon
granules. May be single-button or double-button [12].

Procedure designed to restore breathing after cardiac arrest. Includes clearing air passages to lungs and heart massage [1].

The frequency of an unmodulated transmitter output [12] [18].
