Hello,
I am not sure if this is the place to post this question but i will anyway. If this is not the appropriate place, please tell me where to go.
Okay. I am doing a practical on DC circuits and am not quite certain about the relationship between temperature and resistance?...If there is an increase in the temperature, is there a decrease in the resistance? Because the particles are more mobile and have more energy, thus enabling them to transfer the charge/energy thingo across a resistor faster?
And another: Are the lamps in a motor car usually connected in series or parallel, and why?
I am not sure, but taking a stab in the dark, are they in parallel because if they were in series they would not be able to individually turn on and off as they do on the dashboard.
I will be back on tomorrow, hopefully you can help me.
Thankyou.
Kira
