PARALLEL CIRCUITS

HideShow resource information

Parallel Circuits

  • when components are in parallel:
  • THE TOTAL CURRENT THROUGH THE WHOLE CIRCUIT IS THE SUM OF THE CURRENTS THROUGH THE SEPERATE COMPONENTS
  • eg A1+ A2+A3= the total current

if a comp. has a current of 0.3 amps and another comp. is parallel (ie on top of it) has a current of 0.3 amps as well= the TOTAL CURRENT= 0.6 amps.

  • THE POTENTIAL DIFFERENCE (ie VOLTAGE) ACROSS EACH COMPONENT IS THE SAME.

eg a resistor x is connected to a voltmeter (1) measuring 3V- the other resistor y will also have a voltmeter (2) connected
