In a string of lights, if one light goes out and the others stay lit, which type of circuit do you have?

A parallel circuit

Explanation:

The light bulbs can be connected in two different configurations:

1. Series --> when connected in series, the light bulbs are on the same branch of the circuit. This means that the same current flows through all the light bulbs, while the potential difference across each light can be different.

2. Parallel --> when connected in parallel, the light bulbs are on separate branches of the circuit. This means that the current flowing through each bulb is different, while they all have same potential difference across them.

In the series configuration, when one light goes out, all the other lights also turn off, because they are all on the same branch: so if one breaks, it opens the circuit, and the current can no longer flow through the other lights.

On the other hand, in a parallel configuration, when one light goes out, the other lights stay on, because they are on separate branches, so they are not affected by the broken branch and current can still flow through them.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

the higher the current the higher the mag field around it the higher the influence on the compass
