No. Resistance means to deter or hinder.
RSeries = SummationI=1toN (RI) Simple answer; add them up.
Mark up would mean to add. Mark down would mean to subtract.
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
its the type that cant beat it up
Add all the individual resistance values.
Alloys can add heat resistance to a metal
The new resistance will draw an additional branch current, resulting in an increase in the supply current. Another way of looking at it is, when you add additional resistance, the overall resistance will reduce, increasing the value of the supply current.
its the same as normal resistance, so if you wanted to add the resistors when in parallel you would add them by 1/R1 +1/R2=. If they were in series you would simply add.
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
If they are in series, you need to add the resistance values.
If you add a second resistor, the resistance of series circuit will increase.
I'm not sure what you mean but the angle sum (what all the interior angles add up to) is 180 degrees.
