Electric current element

ammeter

ammeter definition

Measures electric current flowing through circui

voltmeter

voltmeter definition

Measures electric potential

what are the other names for electrical potential?

attention, different electromotive force(emf) And voltage

battery

battery definition

source of EMF (Voltage) And provide electrical potential

when batteries cannot supply current as fast as your circuit drain, sign the solution to this

capacitors

capacitor

capacitor definition

Momentarily stores electric charge/energy for high-drain circuits

diode/rectifier

One-way valve permitting electron flow ONLY

Cathode (-) to Anode (+).

ohmmeter

ohmmeter definition

Measures electrical resistance (opposition to electric current).

ground

ground definition

Safety device providing low-resistance earth path to prevent shock.

resistor

resistor definition

Inhibits/resists electron flow to control current in wire.

rheostat

rheostat definition

Adjustable, variable resistor used in filament circuit (mA selector)

switch

switch definition

Opened (stops current flow) or Closed (allows current flow)

transformer

transform definition

increases or decreases voltage by fixed ratio via electromagnetic induction.

set up transformer

step up transform definition

Fewer primary turns, more secondary turns -> Increases Voltage, decreases Current.

step down transformer

step down transformer definition

More primary turns, fewer secondary turns -> Decreases Voltage, increases Current.

wye (star) transformer

wye (star) transformer definition

Windings connected in Y-shape; supplies 3 power types from 1 source.

Delta transformer

Delta transformer definition

Windings connected in series triangle (∆); supplies 3 power types from 1 source

AC power source

AC power definition

movement or flow of electric charge periodically reverses direction

fuse

fuse definition

Safety device with internal wire that melts ("blows") if current exceeds limit.

direct current

direct current

Low electrons in one direction along a conducted
