Radiation for life
Diapositivas del conjunto (2)
-
- variable resistor or rheostat changes resistance
- longer lengths of wire = more resistance
- thinner wires = more resistance
- voltage measured in volts using a voltmeter connected in parallel
- fixed resistor - as voltage increases = current increasing
- fixed power supply - as resistance increases = current decreasing
- formulas:
- resistance = voltage/Current
- voltage = current x resistance
- current = voltage/resistance
-
- live wire carries high voltage around house
- neutral wire completes the circuit providing a return path for the current
- earth wire
