What is the voltage triangle/formula?
voltage=current x resistance
The current in Series circuit
Current in series circuit is always the same. No matter where you put the ammeter, the amp will be measured the same.
The current in Parallel circuit
Current in parallel is split.
voltage in Series circuit
Voltage in series is split. eg. a 6 volts battery will give 3v to each bulb if there are two light bulbs in the circuit
Voltage in parallel
Voltage in parallel will remain the same. If your battery gives out 6v, and there are two lightbulbs in your circuit, each bulb will both receive 6V
Static electricity
Charges- positive attracts negative, negative attracts positive. Same end will repel each other. Some uses of s.e = spray paint
measured in volts, is the push of electrons. mostly measured in Parallel circuits
measured in amps. is the flow of the elctrons in the circuit
Diode and LDR
Diode- controls one way flow of electricity. LDR - Light dependent resistor. more light shone on LDR, more current flows which means less resistance.
The resistance in a thin, long wire and the resistance in a thick, short wire
The resistance will be small inside a thick short wire because more electrons can get throuhg at a time, and less electron will get through in a long, thin wire, and it will waste more electrons, which means the resistance will increase.
