how does the energy efficiency of wires differ between different materials
physics knowledge
power = voltage * current
Voltage = current * resistance
resistance = resistivity
length
energy efficiency % = output power/input power * 100
different materials
copper
nichrome
zinc
gold
iron
conductivity and resistivity
wires
length
width
area
variables
independent
wire material
dependent
energy efficiency
tested through the energy efficiency formula, ammeter and voltmeter
controlled
wire length
ruler
wire radius
ruler
voltage
voltmeter
current
ammeter
Justification
usage of a voltmeter and ammeter at each end, to find the voltage and current therefore finding the power input and power output
risk
running electricity through non-insulated wires can cause an electric shock
