You can solve this by using the formula:
#R=R_0[1+alpha(T-T_0)]#
Where:
• #R# is the new resistance
• #R_0# is the initial resistance
• #alpha# is the temperature coefficient
• #T# is the new temperature
• #T_0# is the initial temperature
Take a look at our given:
• #R_0=0.36Omega#
• #T=350"°C"#
• #T_0=25"°C"#
Plug these values into the formula.
#[1]color(white)(XX)R=R_0[1+alpha(T-T_0)]#
#[2]color(white)(XX)R=(0.36Omega)[1+alpha(350"°C"-25"°C")]#
#[3]color(white)(XX)R=(0.36Omega)[1+alpha(325"°C")]#
#[4]color(white)(XX)R=(0.36Omega)+alpha(325"°C")(0.36Omega)#
#[5]color(white)(XX)color(red)(R=0.36Omega+alpha(117"°C")Omega)#
Since we don't know the temperature coefficient we can't compute for the actual resistance of Conductor B. However, you can say that the resistance of Conductor B is #color(red)(alpha(117"°C")Omega)# more than Conductor A.
