Answer:
The resultant displacement is the sum of displacement vectors
Explanation:
The vector sum of two or vectors is know as resultant .
The resultant displacement is the result of when displacement vectors are added.
If the vector quantities are same then the two vectors can be added.
The resultant velocity is obtained by adding two or more velocity vectors.
In displacement vector the position will change.
The direction traveled is the direction of the displacement vector .
The magnitude of the displacement vector is the distance from starting point to the ending point.
The role of a resistor in an electrical circuit is to <u>hinder the movement of charge through a circuit</u>
Explanation:
A charge is carried through a wire by current (indicated as <em>I</em> in physics S.I connotation). Higher current means the rate at which the charge is flowing through the wire is fast. High resistance of the wire means the charge flows with difficulty hence slower. Resistance is given by the formulae;
R = V/I whereby;
R = resistance
V = voltage
I = current
As you can observe <em>R</em> (resistance) is inversely proportional to<em> I </em>(current). Meaning the higher the resistance the lower the current.
