In series, only series, the bulb with greatest resistance will draw all the available voltage to use first.
Electrons/ atom: conductors like metal has lots of "free" electrons.
Potential difference is the voltage diff between + and -: E.G: +=12.6; -= 0 => Po. Diff.= 12.6
Individual circuit: Fuse: restrict Amp; bigger the Amp; hotter the heat. As there is no fuse , the 2 big amp will heat up the wire on fire
Short Circuit: wire doesn't go through the bulb(resistance) but shorted 2 earth, will return to Ne- => this will nmaintain a super big Amp n will burn the insultator and set fire.
E.G battery charger broken wire n stuck 2 wire 2gether will get a big shorted circuit
Remember how to check 4 a shorrt circuit.
Variable resistance: use 2 control the Amps.
I: Impedance
WIRE SIZE: Resistance= length * diameter.
Long wire; narrow diameter= high resistance.
good start but I need a reflection on the circuit work you did in practical classes last week
ReplyDeletee.g what circuits did you build, how did you test them, what do the tests indicate--i.e what does this mean
Oh that was just bits and pieces that open my mind in theory class. The official is coming right up sir!
