<u>A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element</u>.
Resistors reduce the current flow and lower voltage levels within circuits.
A <u>circuit is said to be connected in series</u> when the same amount of <u>current flows through the resistors</u>. In such circuits, the voltage across each resistor is different.
In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.
For the above circuit(attached image-1), the total resistance is given as:
The total resistance of the system is just the total of individual resistances.
A <u>circuit is said to be connected in parallel</u> when the <u>voltage is the same across the resistors</u>. In such circuits, the current is branched out and recombines when branches meet at a common point.
A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.
The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here
The sum of reciprocals of resistance of an individual resistor is the total reciprocal resistance of the system.

Remember your kinematic equations for constant acceleration. One of the equations is
, where
= final position,
= initial position,
= initial velocity, t = time, and a = acceleration.
Your initial position is where you initially were before you braked. That means
= 100m. You final position is where you ended up after t seconds passed, so
= 350m. The time it took you to go from 100m to 350m was t = 8.3s. You initial velocity at the initial position before you braked was
= 60.0 m/s. Knowing these values, plug them into the equation and solve for a, your acceleration:
Your acceleration is approximately .

A skater can spin faster by pulling her arms closer to her body or spin slower by spreading her arms out from her body due to conservation of angular momentum.
What is conservation of angular momentum?
- Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an external force, or to put in another way, the speed of rotation is constant as long as net torque is zero.
- Angular momentum, sometimes also referred to as spin, is determined by an object's mass, its velocity and distance of an object's mass from the point of rotation.
- The nearer the mass is to its axis point or the more consolidated it is around that axis the greater its velocity.
