If RT is the total resistance, then:
1/RT = (1/R1) + (1/R2)

How does temperature affect resistance of a wire?
If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
What happens when an electric current encounters resistance?
An electron traveling through the wires and loads of the external circuit encounters resistance.
How do you measure the circulating current in 3 phase parallel system?
The clamp on amp meter has to go around both of the parallel conductors to get an accurate reading of the line current. If you are using a current transformer, both wires have to go through the centre hole in the transformer.
Why the value of armature resistance is low?
Because it is made of pure wire with nothing beyond its length and interaction with its neighboring wires to create resistance
Would thick wires tend to have the least amount of eletrical resistance?
Yes, the resistance is directly proportional to length of wire and inversely proportional Area, hence when Length of wire increases the resistance also increases and when Area increases the resistance decreases. This means a thick wire has least amount of Electrical resistance.
Compared to thin wires electrical resistance in thick wires are?
The electrical resistance in thick wires is less than thin.
How do you arrange 6 identical wires of 6 ohm so that the total resistance is 5 ohm?
Make one resistor parallel with 5 resistors which are in series.
How do you wire a 220 volt motor with 6 wires?
you have to ohm out the wires the start windings will have a higher resistance and the run windings will have a lower resistance if you have 6 wires then you may have a dual motor 1start winding and 2 run windings each having 2 wires the start windings and the run windings are all hooked up in parallel with the start capacitor hooked up in series with the start winding
Thin wires have a what resistance to electron flow than do thicker wires?
Thin wires have a greater resistance rhan thick wires. Imagine a straw. The thinner the straw. the less liquid can get through. Wires work the same way.
Why are automotive wires stranded?
For reducing the resistance for any given length two wire in if parallel will have reduced resistance. And for manageabilityAnswerIt makes cables more flexible.
Does the short or long wire get hottest in a circuit?
This will depend on the circuit configuration, and the wire. For two equivalent types of wire (same covering, thickness, cross section, but different lengths) in a series circuit, where the surrounding on both wires is kept equivalent, heating will be equal per unit length (meaning the wires will reach the same temperature); The longer wire will use more power, which will cause more room heating (due to the longer length), but the wires themselves will reach the same temperature. For the same two wires in a parallel circuit, the smaller wire will heat up more due to a larger current flow through it, thus a higher I^2 * R loss (heat loss) per unit length. If two wires are put in parallel, and have different lengths, but are made to have the same resistance, the exact same amount of current will flow in each, but the shorter one will inherently have a higher resistance per unit length, causing it to become hotter than the longer wire.
What is a parallel circiut?
Something that contains a voltage circuit and wires.
Why do wires turn hot in a circut?
The current passing through them - since all wires have resistance.
Why should the connecting wires in a bulb be of low resistance?
This is to avoid energy losses in the connecting wires.
Why are wires with high resistance used in light and toasters?
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
