circuits

current

using ammeter to measure current, current is in amperes (A).

Voltage

measure voltage using voltmeter (V). Energy in electrons. When current goes through the battery, electrons gain voltage. When current goes through components like filament lamp, voltage decrease. ONLY CONNECT IT IN PARALLEL CIRCUIT

series circuit

single loop circuit, current goes to positive to negative end (Convectional current). All current goes through every component, if one component is brocken the whole circuit is brocken. Amount of current is same everywhere.

Parallel circuit

more than one path, total current is shared for the multiple paths. If one component is broken, the circuit will still work.

LDR

Emmitts light when current flows through it

fuse

breaks if there is too much current flowing through the wire

theromister

changes resistor depending on the termapture

too cold = resistance increase

too hot = resistance decrease.
