combination of resistance
resistance in series : R = R1 +R2+ R3
resistance in parallel: 1/R = 1/R1 + 1/R2 + 1/R3
ohms law V=IR
If temperature around the conducting ends is same
electric current
I = Q/t measured in ampere
potential difference
v = w/q measured in volts
joules law
resistivity
power : rate at which electrical energy is dissipated
